High-pressure sterilizing and homogenizing machine for fluid products

Abstract

The invention relates to a high-pressure sterilizing and homogenizing machine for fluid products, which is used for the sterilization or / and homogenization of drinks, foods, medicines, oil, chemicals and other fluid products. The high-pressure sterilizing and homogenizing machine is composed of at least one unit having the same structure, wherein the one unit has a closed shell; a piston type pressurization chamber and an injection chamber are arranged in the shell; a feed pipe, an injection pipe and a discharge pipe are arranged; the feed pipe is connected with positions above a piston in the pressurization chamber; one end of the injection pipe is connected with positions below the piston in the pressurization chamber, and the other end is connected with the injection chamber; the discharge pipe is connected with the injection chamber; each of the feed pipe and the injection pipe is provided with a one-way valve; the pressurization chamber is closed; a coaxial electromagnetic coil is embedded in the wall of the pressurization chamber, and an outgoing line thereof is connected with a driver; the piston can be driven by a magnetic force in case of no connecting rod and can make a reciprocating motion under the magnetic effect of the coil; a regulating valve and a pressure-flow sensor are arranged; and a cooling medium inlet and outlet pipe is connected to the shell. The invention realizes the continuous operation of respective room-temperature high-pressure material multiple-punch squeezing-injection type sterilization and homogenization having good effects, prevents the entry of bacteria, avoids leakage, ensures that the pressure and flow are controllable and makes equipment simple and reliable.

Description

technical field [0001] The invention belongs to article processing technology, and relates to a high-pressure sterilizing and homogenizing machine for fluid articles, which is used for sterilizing or / and homogenizing fluid articles such as food and beverages, medicines, oil products, cosmetics, chemicals, etc., especially for treating materials at room temperature. Background technique [0002] Existing food, medicine, oil products, cosmetics, chemicals and other fluid products are often processed with heating and sterilization devices, such as pasteurization, heating and pressing, etc., which consume high energy, and the equipment is complex and heavy, and also destroys the heat of raw materials. Sensitive ingredients reduce the quality and flavor of the finished product, and another homogenizer is used for homogenization. There have been advanced devices for high-pressure sterilization and / or homogenization of fluid items, such as application number 201120417282.7 "High-pr...

AI Technical Summary

Problems solved by technology

However, its disadvantages are as follows: 1) The eccentric shaft, transmission rod and piston connecting rod hinge mechanism make the reciprocating stroke of the piston fixed, and the compression ratio of the material in the pressurized chamber remains unchanged. To achieve a certain target high pressure, or to change the target high pressure, it is necessary to change the reciprocating stroke and compression ratio of the piston accordingly, and this mechanism will not work; 2) The piston connecting rod protrudes out of the pressurized chamber by the seal to reciprocate under force, and the seal bears the high pressure of the material And sliding friction, easily damaged, resulting in material leakage and pressure drop; 3) No magnetization, sterilization and probiotic effect on materials; 4) The discharge check valve of the pressurized chamber connected in series with the discharge pipe is pressure-sensitive, which is more complicated; 5) The piston has a connecting rod and connected transmission parts, which cannot rotate on its own axis. It has little shearing and grinding effect on the passing material, and the sterilization and homogenization effect is not good; 6) In order to prevent bacteria from entering the pressurized chamber with the piston connecting rod , it must be connected with a flexible sealing sleeve, which is also vulnerable; 7) The refrigerant passing through the injection chamber does not contact the pressurized chamber and the connected pipeline, which has a poor cooling effect on the material; 8) The piston connecting rod and the driving mechanism are complex, and the pressurized chamber and the injection The chamber and the power are separated from each other, there are many moving parts, the joint between the piston and the connecting rod and the hinge joints of each rod shaft are vulnerable, the noise and vibration are large, the reliability is poor, and the service life is short

These shortcomings make the aforementioned existing high-pressure sterilization homogenizers not practically applied
