Product Introduction

The SD HENGER GROUP HEXFP-ZL1700L Refrigerated Vacuum Tumbler is the marinating station within our complete meat processing line — a horizontal tilting tumbling system for brine absorption, massaging, and protein extraction in medium to large processing plants. Developed on the proven XFP tumbler platform with an integrated glycol cooling circuit, it holds product temperature under control throughout the entire tumbling cycle, protecting protein structure, colour, and microbiological quality during long marinating programs.

With a 1700 L drum handling up to 1000 kg per batch, stepless 2–12 rpm speed control via a Mitsubishi frequency inverter, and vacuum down to -0.085 MPa, the HEXFP-ZL1700L supports both fixed-vacuum tumbling and breathing tumbling (alternating vacuum and atmospheric pressure) to shorten cycle time and improve brine uptake. Control is handled by an OMRON CP-series PLC with a PRO-FACE GP-series touchscreen. Because we build the full line in-house, the tumbler can be specified together with upstream brine injectors and downstream cooking, chilling, and packaging equipment as one coordinated project — with matched capacity, unified utilities, and a single point of responsibility for installation and commissioning.

Core Advantages

Integrated Glycol Cooling with Temperature Display: A dedicated glycol (ethylene glycol) cooling circuit delivers 12000 kcal/h at a -5 °C evaporating temperature, with drum-interior temperature continuously monitored and displayed on the touchscreen. Product temperature stays controlled through extended tumbling programs, which supports consistent texture and colour in the finished product.

Dual Tumbling Modes — Vacuum & Breathing: Operators can select fixed-vacuum tumbling or breathing tumbling, where vacuum and atmospheric pressure alternate. Breathing mode shortens overall tumbling time and improves marinade penetration. A vacuum gauge on the panel shows real-time drum vacuum status down to -0.085 MPa.

Stepless 2–12 rpm Speed Control: A Mitsubishi FR-series frequency inverter provides stepless drum speed adjustment across the full 2–12 rpm range, letting operators match tumbling intensity to each product recipe. Soft-start reduces mechanical shock at startup, which extends drive-train service life and lowers energy consumption.

Low-Speed Mode for Delicate Products: The low-speed setting is intended for products that deform easily under mechanical action — poultry portions, whole birds, and fish products — allowing gentle massaging without structural damage to the muscle.

OMRON PLC + PRO-FACE Touchscreen Control: Control is built on an OMRON CP-series PLC with a PRO-FACE GP-series touchscreen offering water- and moisture-resistant operation for washdown environments. Programs can run in traditional cycle mode (forward tumble – pause – reverse tumble – pause) or in custom mode, where the total run is split into up to six process cycles, each with two independently configurable steps covering time, speed, vacuum state, and rotation direction.

Three Interchangeable Paddle Configurations: V-type paddles suit products needing lighter massaging and impact, such as poultry portions and minced-meat products. Single-blade paddles handle products needing stronger mechanical action, such as large beef and pork primals. Double-helix paddles provide gentle handling with strong whole-drum circulation for whole chicken, whole duck, and emulsified products — giving uniform mixing, high brine absorption, and good elasticity in the finished product.

Complete Loading & Discharge Solution: A mobile loading device handles varied raw-material formats, with track-mounted loading available where several tumblers of the same model run side by side. A dedicated vacuum suction line draws in liquid and dry ingredients, while the hydraulically lifted drum support tilts for complete discharge with no product left behind.

Hygienic SUS304 Construction & Reliable Vacuum System: The whole machine is built from SUS304 stainless steel with a finely polished drum interior, no sanitary dead corners, and full drainage at the discharge position. The vacuum system uses a water-ring vacuum pump with an inline filter and a high-grade vacuum sensor. Direct-coupled gear-motor drive keeps running noise low and transmission efficiency high, while the horizontal tilting layout provides a larger load volume than the RGR-HW series.

Working Principle

The HEXFP-ZL1700L operates through a five-stage programmable tumbling cycle. The machine consists of the SUS304 tilting drum with interchangeable paddles, hydraulic lifting support, water-ring vacuum system, glycol cooling circuit, and PLC electrical control system:

Loading: Raw meat is transferred into the drum via the mobile loading device or a 200 L meat trolley. Brine and dry ingredients are drawn in through the dedicated vacuum suction line, with an optional 500 L suction cart available for large meat blocks or low-moisture minced product.

Vacuum Draw-Down: The lid is closed and the water-ring vacuum pump evacuates the drum to the programmed level, down to -0.085 MPa. The inline vacuum filter and high-grade vacuum sensor maintain a stable, repeatable vacuum condition throughout the run.

Cooling Activation: The glycol circuit circulates coolant through the paddles or the drum jacket, depending on configuration. Drum-interior temperature is monitored continuously and shown on the touchscreen, holding product temperature within the set band for the whole cycle.

Programmed Tumbling: The drum rotates at the programmed 2–12 rpm speed. Operators run either a traditional cycle (forward tumble – pause – reverse tumble – pause) or a custom program of up to six process cycles, each with two independently configurable steps for time, speed, vacuum state, and rotation direction. Breathing mode alternates vacuum and atmospheric pressure to accelerate brine uptake.

Discharge: On program completion, vacuum is released and the hydraulic support tilts the drum to the discharge position. Reverse rotation moves product out through the opening, and the sloped geometry allows complete discharge and full drainage during washdown.

Application Scenarios & Industry Cases

The HEXFP-ZL1700L is deployed as the marinating stage in complete processing lines across the following operations, and can be supplied either as a standalone machine or as part of a turnkey project:

Cooked & Cured Meat Plants: Marinates and massages ham, bacon, cured pork, and cooked-meat raw materials, improving brine distribution and yield ahead of cooking or smoking.

Poultry Processing Plants: Handles whole chicken, whole duck, and poultry portions using low-speed mode with V-type or double-helix paddles, keeping delicate muscle structure intact during marinating.

Beef & Pork Primal Processing: Single-blade paddles deliver the stronger mechanical action needed for large beef and pork primals, breaking down muscle fibre for improved tenderness and brine absorption.

Prepared & Marinated Food Producers: Supports multi-recipe production through programmable cycles — different products can run different speed, vacuum, direction, and timing profiles without hardware changes.

Seafood & Fish Processing: Low-speed tumbling with gentle paddle configurations suits fish fillets and seafood products that deform easily under mechanical stress.

Central Kitchens & Ready-Meal Factories: Produces consistent batches of pre-marinated protein for centralised meal assembly, with temperature control supporting cold-chain and food-safety requirements.

Optional Accessories & Configurations

The following accessories can be supplied alongside the HEXFP-ZL1700L to complete the tumbling workstation:

500 L Vacuum Suction Cart: Mobile cart connected to the drum via vacuum line. Speeds up ingredient loading and is particularly effective for large meat blocks and low-moisture minced product.

Frequently Asked Questions (FAQ)

Q: Does the machine include its own refrigeration unit?

A: The standard configuration assumes the customer supplies the cold source. A dedicated ethylene-glycol refrigeration unit (12000 kcal/h, 3.75 kW / 5 HP, 1250 × 750 × 1250 mm, DN25 connection) is available as an optional accessory where no central cold source exists on site.

Q: What is the difference between vacuum tumbling and breathing tumbling?

A: Vacuum tumbling holds the drum at a fixed vacuum level throughout the cycle. Breathing tumbling alternates between vacuum and atmospheric pressure, which shortens overall tumbling time and improves marinade penetration into the muscle. Both modes are selectable from the touchscreen.

Q: Which paddle configuration should I choose?

A: V-type paddles suit products needing lighter massaging, such as poultry portions and minced-meat products. Single-blade paddles suit products needing stronger action, such as large beef and pork primals. Double-helix paddles handle whole chicken, whole duck, and emulsified products with gentle action, strong whole-drum circulation, and high brine absorption. We can advise based on your product mix.

Q: How flexible is the program control?

A: Beyond the traditional forward–pause–reverse–pause cycle, the custom mode divides total run time into up to six process cycles, each containing two steps. Time, drum speed, vacuum state, and rotation direction are set independently for every step, which allows one machine to cover a wide product range.

Q: What is the actual batch capacity?

A: The drum volume is 1700 L with a rated batch load of 1000 kg. Effective load depends on product density and the paddle configuration fitted; we recommend confirming against your specific product during technical consultation.

Q: Is manual or automatic lid better for my line?

A: Manual-lid units use a 1.5 kW hydraulic system and carry a lower initial cost. Automatic-lid units use 2.2 kW hydraulics and reduce operator workload on lines running frequent batch changeovers. Spare-parts kits differ slightly between the two configurations.

Q: How is the machine cleaned?

A: The drum interior is finely polished with no sanitary dead corners, and the tilted discharge position allows complete drainage. The whole machine is SUS304 stainless steel, and the PRO-FACE touchscreen is rated for water- and moisture-resistant operation in washdown environments.

Q: What after-sales support is provided?

A: We provide a 12-month warranty on the whole machine (wear parts excluded), remote video technical support, on-site installation, commissioning and operator training for export projects, and long-term supply of original spare parts including the standard seal and gasket kit. Our Malaysia branch supports customers across Southeast Asia.

Q: Can this tumbler be supplied as part of a complete processing line?

A: Yes. We manufacture the full line in-house — slaughtering, cutting, brine injection, tumbling, cooking, chilling, and packaging. The HEXFP-ZL1700L can be specified as a standalone machine or integrated into a turnkey project with matched capacity across stages, unified utility planning, coordinated installation, and a single point of responsibility for the whole line.
