Vacuum system in food vacuum enema machine

At present, in the food processing machinery that needs vacuum filling, especially in the product machinery for red sausage, there are many disadvantages in the vacuum regulation degree

① Some of them only have the function of vacuumizing, but their regulating ability is poor;

② Some can adjust the vacuum degree, but by manual adjustment, the work efficiency is very low, and the operation is complex, so the accuracy of vacuum degree is reduced. In order to solve the above technical problems, we recommend the application of vacuum system in vacuum enema machine.

Vacuum enema machine is a vacuum filling machine with quantitative filling and high-speed twisting. It can effectively prevent fat oxidation, avoid protein hydrolysis, reduce the survival of bacteria, effectively ensure the shelf life of the product, bright color and pure taste.

The source of vacuum pumping power is the continuous operation of vacuum pump. Through PLC program control, when one of the solenoid valves is in the closed state, the other solenoid valve is just in the open state. Through the hard connection pipeline, the water distribution filter, soft connection pipeline, solenoid valve, vacuum chamber and other key components are connected into a closed vacuum channel, so the vacuum in the vacuum chamber rises sharply The data of void rise is sent to the touch screen controlled by PLC by the signal from vacuum sensor. The upper and lower limits of vacuum degree can be set on the touch screen. When the signal sent by the vacuum sensor to PLC reaches the upper limit value of the vacuum degree, PLC will send the signal to the solenoid valve to make it open. At the same time, the ball valve is also in the open state. At this time, the vacuum pipe is in the open state, so the vacuum degree decreases. When the vacuum sensor sends the signal to the PLC, the signal will be opened When the PLC signal reaches the lower limit value of vacuum degree set by the touch screen, PLC sends a signal to the solenoid valve to make the solenoid valve in the closed state, so the vacuum degree rises, thus forming the ability of vacuum automatic regulation.

vacuum pump selection:

According to the requirement of vacuum degree for the special vacuum system of vacuum enema machine, the limit vacuum degree of vacuum pump is usually selected to be one order of magnitude higher than the vacuum degree required by the equipment. Because the pressure range of the system is required to work normally, the pressure range of the vacuum pump must meet the working pressure required by the equipment. According to the specific situation of the extracted gas is water vapor and impurities, whether to limit the requirements of oil steam when the system is working. The pumping capacity of vacuum pump system: it is the main basis for choosing a certain type of vacuum pump.

Compared with the traditional vacuum enema machine, the vacuum system has the following advantages:

① The vacuum signal is collected by vacuum sensor and sent to PLC controller. The closing state of solenoid valve is controlled by program. The appropriate range of vacuum degree is input by touch screen. The automatic adjustment function of vacuum degree of vacuum enema machine is fully realized, and the regulation precision of vacuum degree is improved;

② It improves the labor efficiency, reliability and practicability of the products.
