Working Principle

This machine operates on the principle of high-speed centrifugal force. An electric motor drives the dehydration chamber to rotate at high speed, causing moisture or fat within the ingredients to be rapidly flung outward under centrifugal force and expelled through perforations in the chamber wall. The separated liquid is promptly discharged through a large-diameter drain outlet, thereby achieving thorough dehydration or defatting of the ingredients.

The equipment is equipped with an adjustable timer and variable-frequency speed control. Users can freely set the operating time and rotational speed according to the characteristics of different ingredients, ensuring optimal dehydration/defatting rates while maximizing the preservation of the ingredients’ shape and preventing damage.

Structural Components

Stainless Steel Lid: Designed to be dust-proof and splash-proof, it effectively prevents water and oil from splashing during operation while keeping dust from contaminating the ingredients.
Food-Grade Stainless Steel Centrifuge Bowl: Corrosion-resistant and high-pressure-resistant, with a smooth interior for easy cleaning, ensuring uniform dehydration and degreasing of ingredients and meeting food safety standards.
Large-Diameter Drain Outlet: Rapidly discharges separated water or oil, improving processing efficiency and preventing residual liquids from causing ingredients to become re-moistened or greasy.
One-Button Control Panel: Features microcomputer-controlled buttons for simple and convenient operation; no professional training is required to use it.
Time Relay Controller: Allows for flexible adjustment of operating time based on ingredient type, precisely controlling the dehydration/de-oiling results and enhancing processing efficiency.
Rubber shock-absorbing base: Effectively dampens vibrations caused by uneven loading of the inner bowl, ensuring smooth operation and reducing wear on the machine body.
Heavy-duty spindle and bearings: Constructed from high-strength, premium steel and equipped with dual bearings and thrust ball bearings, these components minimize wear, reduce energy consumption, and extend the equipment’s service life.
Adjustable leveling feet: Allow flexible adjustment of the equipment’s level to suit the site conditions, preventing shaking and noise during operation.
All-Stainless Steel Body: Except for the hydraulic components, the entire machine is constructed from food-grade stainless steel, eliminating hygiene dead zones, facilitating easy cleaning, and meeting food processing hygiene standards.

Product Advantages

Smooth, Safe, and Quiet Operation: Rubber shock absorbers and adjustable feet, combined with a sealed design, electromagnetic brakes, and anti-static transmission, effectively reduce vibration and noise while ensuring operational safety.
Highly Efficient, Labor-Saving, Cost-Effective: One-touch start, automatic timing, and variable-frequency speed control make it dozens of times more efficient than manual labor, significantly reducing the need for manpower.
Versatile and multi-functional: Suitable for vegetables, fruits, seafood, meat, fried foods, and more. Capable of processing granular and fibrous materials, it adapts to a wide range of processing scenarios.
Durable and easy to maintain: The food-grade stainless steel body, paired with high-strength spindles and bearings, features a simple structure that is easy to disassemble and reassemble, resulting in low failure rates and a longer service life.
Optional explosion-proof design: The sealed structure can be equipped with nitrogen purging and anti-static systems to meet the requirements of special environments involving flammable, explosive, or toxic materials.
Gentle processing preserves product appearance: The low-shear design efficiently removes water and oil while maximizing the retention of the ingredients’ shape and integrity, ensuring no damage to the material.

Applications of Centrifugal Dehydration and Deoiling Machine

Centrifugal dehydration and de-oiling machines are widely used in vegetable processing plants, central kitchens, restaurant chains, frozen food factories, snack food manufacturers, and ready-to-cook meal producers. They are suitable for dehydrating and de-oiling various types of ingredients, including:

Vegetables: Fresh vegetables such as lettuce, Chinese cabbage, spinach, carrots, potatoes, onions, and celery, as well as semi-finished vegetable products that have been washed and cut.
Fruits: Fresh fruits such as grapes, cherries, strawberries, diced mangoes, and diced apples. This process removes surface moisture, facilitating subsequent processing or packaging.
Seafood: Shrimp, squid, fish fillets, shellfish, etc. Dehydration makes these products easier to freeze, marinate, or cook, while de-oiling removes excess oil from the surface of fried seafood.
Meat: Cooked meat, meat strips, meat chunks, etc. Dehydration removes surface moisture, while oil removal treats fried meats to reduce fat content.
Fried Foods: French fries, potato chips, fried snacks, and oil-soaked ingredients. Effectively removes excess surface oil to enhance texture and reduce fat content.

Machines You May Also Be Interested In

Fruit and Vegetable Washing Equipment: Bubble washers, drum washers, spray washers, etc. After washing, the produce proceeds directly to the dehydrator, improving processing efficiency.
Cutting Equipment: Commercial vegetable cutters, dicers, slicers, shredders, etc. After cutting, the ingredients undergo dehydration or oil removal to prepare them for subsequent processing.
Blanching and Steaming Equipment: Blanchers, pasteurization tunnels, etc. After processing, the ingredients are dehydrated to facilitate cooling and packaging.
Frying Equipment: Continuous fryers, commercial fryers, etc. After frying, the ingredients undergo immediate oil removal to reduce fat content.
Packaging Equipment: Vacuum packaging machines, nitrogen-flushed packaging machines, etc. Ingredients are packaged immediately after dehydration/de-oiling to extend shelf life.
Conveying Equipment: Belt conveyors, screw conveyors, etc., enabling automatic transfer of ingredients between equipment and reducing manual handling.
Storage Equipment: Stainless steel storage tanks, mixing tanks, etc. Dehydrated/de-oiled ingredients can be stored directly, facilitating subsequent processing or storage.
