Embodiment 1

[0018] The bowl porridge automatic sterilization process of the present embodiment is realized through the following steps:

[0019] The first stage of hot water cooling and heating up stage: use steam to heat the water in the water storage tank to 90-95 °C, use this hot water to discharge from the bottom of the sterilizer to the top, and the discharged water enters the water storage tank again, and circulates after heating up When used, the cooling time is preferably 5 to 15 minutes. Using hot water for cooling can eliminate the cold spot in the autoclave and make the temperature in the autoclave uniform. The steam valve and the vent valve are controlled by the PLC control system. When the cooling is completed, the steam valve is opened, and saturated superheated steam is introduced into the autoclave from the top to drain water and heat up. During the temperature rise process, the pressure is kept at 0.18MPa~0.23MPa , The pressure adjustment accuracy is between 0.005 ~ 0.03...

Abstract

The invention provides an automatic bowl porridge sterilizing process. The automatic bowl porridge sterilizing process comprises the following steps: a cooling and heating stage; a sterilizing stage; a back-pressure cooling stage. The automatic bowl porridge sterilizing process is realized by setting corresponding sterilizing parameter values through a PLC automatic control system. Compared with the similar technologies, the automatic bowl porridge sterilizing process is low in sterilizing temperature, short in sterilizing time, capable of turning over porridge cans, high in heat conductions speed and regular in pressure changes. The automatic bowl porridge sterilizing process is adopted to sterilize plastic bowl porridge cans, so that the content is pasted and high in pasting degree, and thus, the porridge bowel is ensured to not deform, and the optimal sterilizing effect is achieved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to an automatic sterilization process for bowl porridge. Background technique [0002] In industrial production, in order to ensure the waxy and soft state of porridge, attractive color and long shelf life, high pressure and high temperature are often used for a long time to maintain the porridge in a good state for a long time. However, the traditional sterilization process has a large pressure range and the sterilization time Long, energy consumption is big, thereby increased production cost. However, canned porridge in bowls is greatly affected by pressure changes, which is prone to problems such as bowl bursting. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides an automatic sterilization process for bowl porridge, which solves the technical problem of high-temperature and high-pressure sterilization o...
