The process is automatic and does not require operator supervision. In addition, the machine itself manages the lack of product supply, stopping and restarting independently. The product is fed into the vertical hopper; the forming chamber is fed with a horizontal cylinder.
All movements are managed by electric cylinders with brushless motors. In this way, it is possible to control all parameters of the process, first of all the pressure and speed with which the product is pressed – these parameters are essential to manage residual water in the final product.
Like almost all semi-finished products, the product is packaged aseptically. Also, in this field we can count on the experience of hundreds of installations.
The subsequent concentration phase takes place in the evaporators. The choice of evaporator is fundamental to guarantee the quality of the product and economy of the process. For this reason, we create multiple-effect evaporators, with forced circulation and falling film, also with thermal re-compression (TVR) or mechanical re-compression (MVR). For more delicate products, we offer […]
A different process takes place to produce clear juice: For the squeezing phase, presses are used to obtain less pulpy juices, at the cost of a lower yield, suitable for the following phase of precipitation and ultrafiltration. For citrus fruits, we collaborate with leading companies in the sector for the process of pressing, and separation […]
Next, the chopping phase, or stoning, inactivation, and refining. The process does not always follow this order. For example, for apples, sometimes refining is done first in a controlled environment, to limit oxidation of the product.
The stage of receiving, washing, and sorting of raw material is very similar for the different types of fruit.
The concentrate is sent from the evaporator to the sterilization line tank. From here, it is pumped at high pressure first into the sterilizer-cooler, and afterwards, into the aseptic filler, to fill all available sizes into already sterilized bags.
The juice inside the evaporator goes through several stages – its concentration level will be increased gradually; the desired density will be obtained in the final, or “finisher”, stage. The entire concentration process takes place in multi-stage evaporators, sized to preserve the characteristics of the product, and lengthen the working time between successive washings. Fenco […]
