Full-automatic sterilizing quality-guaranteeing steamer and sterilizing technology

Abstract

The invention relates to a full-automatic sterilizing quality-guaranteeing steamer and a sterilizing technology which are suitable for sterilizing and quality guaranteeing of fully closed box-packed fast food. The steamer comprises a pot body, a pot cover, a steam pipe, a return water storage tank, a vent pipe, a water cycle pipeline and a drain pipe, wherein the water cycle pipeline comprises a return water pipe, a chief spray pipe, a water inlet pipe and a water outlet pipe, the pot body is provided with a thermometer I, a pressure gauge I, a water-thermometer I and a reducing valve I, and is connected with an automatic control box, the pot cover is hermetically connected with the pot body, the pot body is connected with the steam pipe, the vent pipe, the chief spray pipe and the water outlet pipe, the return water storage tank is connected with the return water pipe and the vent pipe, the drain pipe is communicated with the water outlet pipe, the inner cavity of the pot body comprises a temperature control sensor, a water outlet hole, a steam heating pipe, an upper spray pipe and a side spray pipe, and the upper spray pipe and the side spray pipe are communicated with the chief spray pipe. The steamer can be used for automatically and accurately controlling the temperature, pressure and time, guaranteeing the sterilizing quality through heating and cooling by gradient, and saving energy and water because the hot and cold spray water is used and stored reasonably.

Description

technical field [0001] The invention relates to a fully automatic sterilizing and quality-preserving steamer and a sterilizing process, which are mainly suitable for sterilizing and quality-preserving fully enclosed boxed fast food, and belong to the technical field of food industry. Background technique [0002] The fully enclosed boxed fast food box is made of high temperature resistant, high barrier, and easily degradable food-grade polymer materials. After the food is placed in the fast food box, it is sealed with a food-grade polymer material coating; the boxed fast food is filled with nitrogen by vacuum , high-temperature sterilization, so that the product has a long shelf life at room temperature, generally 6 months; boxed fast food has the characteristics of good sealing, heat resistance, and easy tearing, which is convenient for storage and transportation, and has a long shelf life. [0003] In the prior art, there is no sterilizing and quality-guaranteed steamer sp...
