Fruit juice production process: the fruit - > check level weighing - > GuoChi - - - - > cleaning of hydraulic transportation - - choose - - spray - - crushing - - enzyme treatment - - pressing - - pasteurization degumming - - ultrafiltration - - - - - - pasteurization - evaporating and aseptic filling. The main equipment of juice production is mainly three parts: 1, juicing, 2, degumming treatment + ultrafiltration, 3, concentration. The most critical equipment in juice production is the juicing equipment. So-called juice, is to promote an object (extrusion), the composed of solid, liquid and gas substances of a mixture of liquid and gas substances (extrusion chamber) from a limited space in the process of squeezing out. If the extruding device is reasonable, the gas and liquid material can be squeezed out of the extrusion chamber, while the solid material remains in the extrusion chamber. The factors that influence the juice rate are: 1. Extrusion pressure: in a certain pressure range, the outflow rate is directly proportional to the extrusion pressure. But this range is critical. 2. The crushing degree of pulp mud is 3, the thickness of the extruded layer 4, the pre-discharge juice 5, the auxiliary agent of juicing, have no auxiliary agent, which affects the juice rate up to 11.7%.

 

    The comparison of various kinds of juicing equipment: intermittent: chamber type juicer, package juicer, continuous: spiral juicer, belt juicer. 1. Spiral juicer, which is widely used in China, has a simple structure, little fault and high production efficiency. But the juice rate is low, mostly 40 to 60%, turbidity >3%. 2. Belt type juicer, continuous operation, high efficiency, suitable for mass production. The juice yield is about 78%. The belt type juicer is the most advanced juicer for juice production at home and abroad. Due at the beginning of the juice contains more turbid, influence of fruit juice concentrate and the final product quality, the need for early juice purification treatment, ultrafiltration equipment, mainly in all kinds of separation and separation in the clarification process, in order to improve the separation factor and efficiency. Enrichment, after purification, the fruit juice, under the high vacuum degree, within 60-65 ℃ environment temperature, evaporation of most moisture content in the fruit juice, to reduce the volume of about 1/6 of the original volume, soluble solid content from general around 12% to 12%. Easy to transport and save. At present, the price of various kinds of concentrated juice concentrate in the domestic market is generally around 1.0-12,000 yuan. The above is a simple description of the fruit concentrate process.
