Grape juice machine industry knowledge

The core of the industrial spiral fruit and vegetable juicer is the low-speed spiral extrusion technology, which continuously compresses the material through the screw shaft with variable pitch and diameter, and realizes the separation of juice and residue, instead of cutting at high speed by the blade. ‌‌

• Feed propulsion: the material enters the press chamber from the feed hopper, and the screw shaft rotates to push the material forward.
• Step-by-step compression: the spiral pitch gradually decreases, the spindle diameter increases, and the internal volume continues to decrease, forming a step-by-step increasing extrusion force on the material.
• Separation of juice and residue: the juice flows out through the screen and is collected, and the solid residue continues to be pushed forward and discharged from the residue outlet.
• Dryness adjustment: By adjusting the spring or hydraulic pressure behind the tap cone, the slag resistance can be controlled and the wet and dry degree of slag can be flexibly adjusted. ‌‌

• Single screw juicer: compact structure, suitable for conventional fruits and vegetables such as apples, tomatoes, pineapples, carrots, ginger, etc. The standard filter hole is about 0.5 mm, and the processing capacity can reach 1.5 tons/hour.
• Double-screw extruder: two counter-rotating screw shafts are squeezed like "twisting towels", with higher juice yield, which is suitable for materials with more fiber or viscosity (such as grape skin residue, sea buckthorn fruit, spinach, Chinese medicine residue, kitchen waste, etc.).
• Belt juicer: Based on the principle of continuous pressure filtration, the materials are clamped by the upper and lower filter belts and pressurized step by step by several groups of rollers, which is suitable for apples, pears, grapes and other fruits, with continuous operation and low energy consumption. ‌‌

• Material: 304 stainless steel is usually used in the contact part with materials, and 304 stainless steel should be used in the whole machine when the requirements of food-grade scenes are higher.
• Juice yield: the juice yield of some fruits and vegetables can reach 85% under the screw extrusion technology, which is much higher than the traditional extrusion method.
• Processing capacity: Single-screw models are about 1.5 tons/hour, double-screw models range from 0.5 tons/hour to 20 tons/hour, and large equipment can reach 40 tons/hour.
• Automation: High-quality manufacturers will be equipped with functions such as automatic deviation correction, adjustable pressure, adjustable speed, fault alarm, etc., and support PLC intelligent control, which can be directly connected to the whole factory automation production line. ‌‌

The grape juice machine industry is a vibrant and rapidly evolving sector within the broader food and beverage equipment market. Grape juice machines are specialized devices designed to efficiently extract juice from grapes, preserving the natural flavors, nutrients, and antioxidants that make grape juice a popular and healthful choice among consumers worldwide.
