Food pasteurization machine

Abstract

The invention discloses a food pasteurization machine to solve the problems of inconsistent water temperature at each position in existing sterilization tanks, poor sterilizing effect, low steam heat utilization rate, and quality reduction caused by abrupt temperature drop of food packaging containers. The food pasteurization machine comprises a frame, which is provided with a preheating tank, a sterilizing tank, a precooling segment and a cooling tank in order. The preheating tank, the sterilizing tank, the precooling segment and the cooling tank are equipped with a conveying belt. The sterilizing tank includes a bottom plate, two side plates and two inclined plates. The bottom plate is provided with a water inlet and a water outlet, and the bottom plate, the side plates and the inclined plates are connected together to form the sterilizing tank. A steam spraying pipeline is uniformly distributed on the bottom plate and in connection with an external boiler, and is provided with one-way valves. The food pasteurization machine provided by the invention can ensure consistent water temperature in the sterilizing tank, improves the sterilizing effect, ensures food security, also can improve the heat utilization ratio of steam, and is especially suitable for processing by salted pickles, pickles and other food enterprises.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a food pasteurization machine. Background technique [0002] Pickles and pickles are very popular among people and are indispensable foods on the table. During the production of pickles and pickles, it is necessary to sterilize the bottled food to ensure the safety of pickles and pickles. [0003] The invention patent with the application number 200410088335.X discloses a pasteurization equipment for pasteurizing products in containers, which are processed in a container flow through at least sections for heating, pasteurization and cooling With the help of spray liquid treatment, the pasteurization equipment has a sterilizer shell and a conveying device, a spray device, a water tank, and a pump arranged in the sterilizer shell, and the tunnel shell is in a modular structure, consisting of any number of Flexible, exchangeable segment construction, wherein the segments...

AI Technical Summary

Problems solved by technology

[0008] The existing pasteurization machines use high-temperature water to sterilize the bagged food in the sterilization tank. However, when the bagged food just enters the sterilization tank, due to the large temperature difference, the heat absorbed by the bagged food Larger; the heat absorbed by the bagged food becomes smaller when the temperature rises, which causes the water temperature in the inlet section of the sterilization tank to drop faster, while the water temperature in the outlet section drops slower, resulting in inconsistent water temperature in each position of the sterilization tank

Although there is a temperature sensor in the sterilization tank to detect the water temperature in the sterilization tank, the temperature sensors are all set at relatively fixed positions in the sterilization tank, so it is impossible to accurately detect the water temperature in the sterilization tank, thereby affecting the sterilization Effect

[0009] There are also some pasteurization machines that spray high-temperature steam onto the food by installing a steam spray pipe above the sterilization tank to perform sterilization treatment. This structure not only results in low heat utilization rate of the steam, but also has uneven sterilization, resulting in The problem of poor sterilization effect
