The fruit processing line refers to the cleaning, lifting, sorting, crushing, peeling and pitting, beating and other pre-processing of the original fruit, to vacuum concentration, ultra-high temperature sterilization, aseptic filling to aseptic large bags of concentrated sauce or concentrated juice and other production lines of all or part of the equipment.The food sterilizing machine is a machine that takes food raw materials and processed products as the object. Through the sterilization and sterilization of microorganisms, the main factors that cause food deterioration, to stabilize food quality, effectively prolong the shelf life of food, and reduce the The number of harmful bacteria in food is surviving, and the ingestion of live bacteria can cause human (usually intestinal) infection or pre-produced bacterial toxins in food to cause human poisoning. The material is heated to 138-150°C through a casing heat exchanger in a continuous flow state, and is maintained at this temperature for a certain time (2-4 seconds) to achieve commercial sterility levels, and then in a sterile state. Filled in sterile packaging containers in a sterile environment. The entire sterilization process is completed in an instant at high temperature, which completely kills microorganisms and spores that can cause material spoilage and deterioration, and at the same time, greatly preserves the original flavor and nutrients of the food. This strict processing technology and precise processing method of equipment can effectively prevent the secondary pollution of food and greatly prolong the shelf life of the product. The UHT process preferably adopts the in-line casing heat exchanger sterilization system, because of its reliable working performance under high steam pressure and ultra-high temperature, especially the continuous working time can be as long as more than ten hours, thus achieving better performance than plate type heat exchangers.
A juice extracting machine, also known as a juice extractor, is a tool used to extract juice from fruits, herbs, leafy greens and other types of vegetables in a process called juicing. It crushes, grinds, and/or squeezes the juice out of the pulp. Some types of juicers can also function as a food processor. Most of the twin gear and horizontal masticating juicers have attachments for crushing herbs and spices, extruding pasta, noodles or bread sticks, making baby food and nut butter, grinding coffee, making nut milk, etc. Juice extracting machines are used for squeezing juice from citrus such as grapefruits, lemons, limes, and oranges. Juice is extracted by pressing or grinding a halved citrus along a juicer's ridged conical center and discarding the rind. Some reamers are stationary and require a user to press and turn the fruit, while others are electrical, automatically turning the ridged center when fruit is pressed upon.
An evaporating machine is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form - vapor. In this process, the liquid is evaporated, or vaporized. The solution containing the desired product is fed into the evaporator and passes across a heat source. The applied heat converts the water in the solution into vapor. The vapor is removed from the rest of the solution and is condensed while the now-concentrated solution is either fed into a second evaporator or is removed. The evaporator, as a machine, generally consists of four sections. The heating section contains the heating medium, which can vary. Steam is fed into this section. The most common medium consists of parallel tubes but others have plates or coils typically made from copper or aluminium. The concentrating and separating section removes the vapor being produced from the solution. The condenser condenses the separated vapor, then the vacuum or pump provides pressure to increase circulation.
One example of an evaporator is a radiator coil used in a closed, compressor-driven circulation of a liquid coolant. This is called an air-conditioning system (A/C) or refrigeration system. It allows a compressed cooling chemical, such as R-22 (Freon) or R-410A, to evaporate/vaporize from liquid to gas within the system while absorbing heat from the enclosed cooled area in the process, for example a refrigerator or air conditioner. This works in the closed A/C or refrigeration system with a condenser radiator coil that exchanges the heat from the coolant, such as into the ambient environment. A different kind of evaporator can be used for heating and possibly boiling a product containing a liquid to cause the liquid to evaporate from the product. The appropriate process can be used to remove water or other liquids from liquid based mixtures. The process of evaporation is widely used to concentrate liquid foods, such as soup or make concentrated milk called "condensed milk" done by evaporating water from the milk. In the concentration process, the goal of evaporation is to vaporize most of the water from a solution which contains the desired product.
The traditional filling machinery mostly adopts mechanical control, such as cam distribution shaft, and then there are photoelectric control, pneumatic control and other control forms. However, with the increasing improvement of food processing technology and the increasing requirements for packaging parameters, the original control system has been difficult to meet the needs of development. New technology should be adopted to change the appearance of food packaging machinery. Today's food filling machine is a mechanical and electronic equipment integrating machine, electricity, gas, light and magnetism. In the design, we should focus on improving the automation of packaging machinery, combine the research and development of packaging machinery with computers, and realize mechatronics Control. The essence of Mechatronics is to organically combine machinery, electronics, information, detection and other related technologies from a system point of view and using the principle of process control to realize the overall optimization.
