High-end screw press dehydration equipment manufacturer
Screw Press Dehydrator (Screw-type Fruit and Vegetable Juicing Equipment) – Industrial-Grade Juicing Solutions
The screw press dehydrator is an industrial-grade continuous dehydration equipment that separates solids and liquids through physical extrusion. It is widely used in fruit juicing, vegetable juicing, pomace dehydration, plant extract processing, pectin production, and pre-fermentation treatment for fruit wine. For fruit and vegetable processing enterprises requiring continuous operation and high-volume juicing, the screw press dehydrator is a crucial piece of equipment in the production line.
With the rapid development of fresh juice, NFC juice, and deep processing of fruits and vegetables, enterprises have increasingly higher requirements for high juice yield, low energy consumption, low maintenance costs, and continuous production. The screw press dehydrator, with its simple structure, high output, high juice yield, no consumables, and wide applicability, has become the ideal juicing equipment for fruit and vegetable processing projects.
Screw press dehydrators (screw juicers) are suitable for most fruit and vegetable raw materials that can be crushed into pulp, including high-juice, low-juice, high-fiber, and multi-seed varieties.
Suitable Fruits:
Apples, pears, peaches, plums, loquats
Grapes, blueberries, mulberries, blackcurrants, and other berries
Citrus fruits such as oranges, lemons, grapefruits, and other citrus fruits
Pineapples, kiwis, passion fruit (juicing/dehydration including shell)
Mangoes, papayas, bananas, and other high-pectin, high-fiber fruits
Suitable Vegetables:
Tomatoes, carrots, cucumbers
Celery, spinach, leeks, and other fibrous vegetables
Potatoes, ginger, pumpkins, and other high-hardness materials
Suitable By-products and Extended Uses:
Fruit pomace dehydration (apple pomace, grape pomace, orange peel pomace)
Pre-treatment for pectin extraction
Solid-liquid separation of enzymes and fermentation broths
Feed fiber dehydration
Dehydration of medicinal herb residues and food waste
Basically, anything that can be crushed into pulp can be squeezed, dehydrated, or juiced using a screw press.
Advantage 1: Continuous Juicing Structure, Large Processing Capacity
Compared to traditional pressing, screw presses support continuous feeding and continuous juice output, with a processing capacity of:
0.5–20 tons/hour. Suitable for the large-scale production needs of juice factories, beverage factories, and large-scale fruit and vegetable processing enterprises.
Advantage 2: High Juice Yield, Precisely Adjustable According to Material
By adjusting:
Back pressure device
Screw structure (variable pitch design)
Screw mesh size
The juice yield of most fruits and vegetables can reach 65–90% (this may vary depending on the juice content). Higher juice yield means that enterprises can significantly reduce raw material costs and improve economic efficiency.
Advantage 3: Low-Temperature Mechanical Extrusion, Preserving More Juice Flavor
Screw extrusion is a gentle process that does not produce a significant temperature rise and does not damage the juice flavor, making it suitable for producing NFC juice, jam, and fruit and vegetable beverages.
Advantage 4: No consumables required, low maintenance cost. The equipment requires no filter cloth, filter plates, filter paper, or other consumables, resulting in lower long-term operating costs.
Advantage 5: High residue-liquid separation rate, reducing downstream filtration pressure. The moisture content of the fruit pomace after juicing can be reduced to 55-65%, significantly reducing: centrifuge load, clarification filtration pressure, and downstream filtration consumable consumption. This saves energy and labor costs for the entire production line.
Advantage 6: High material adaptability, multi-purpose. Whether it's high-fiber (celery, leeks), high-pectin (mango, banana), multi-seed (passion fruit), loose grains (grapes, blueberries), or hard grains (ginger, carrots), the screw press can work stably and is not picky about materials, making it one of the most versatile pressing equipment for fruit and vegetable processing plants.
Advantage 7: Flexible configuration, customizable to process requirements
Supports multiple personalized designs:
Screw size 0.3–2mm
304/316 stainless steel
Larger feed hopper
Variable diameter screw structure
Bottom juice collection system
Customized models can be customized for juice factories, jam factories, and pomace processing lines.
The screw press dehydrator (screw juicer) achieves solid-liquid separation by gradually decreasing the pitch of the screw shaft, causing the material to be continuously compressed within the pressing chamber. Its core process is:
1. Material feeding (crushed fruit pulp enters the main unit)
2. Screw pushing and squeezing (gradually decreasing volume)
3. Juice discharged through the filter screen
4. Pomace discharged from the pomace outlet (adjustable back pressure controls dryness and moisture content)
This structure is simple, stable in operation, and less prone to failure, making it suitable for high-intensity continuous production.
