Superheated steam sterilization equipment and superheated steam sterilization method

Abstract

The invention discloses superheated steam sterilization equipment which comprises a sterilization container in which a material to be sterilized can be contained and a steam generation device for supplying steam to the sterilization container, wherein the steam generation device is a superheated steam generator (1); the superheated steam generator (1) comprises a steam generator (2) capable of generating saturated steam and a steam heater (3) for heating the saturated steam into superheated steam; the superheated steam can be used for directly heating and sterilizing the material in the sterilization container. The invention also discloses a superheated steam sterilization method which comprises the steps of (1) processing preparation; (2) material feeding of a processing kettle; (3) sterilization by the superheated steam; (4) material discharging; and (5) repeating of the steps from (2) to (4). The superheated steam sterilization equipment and the superheated steam sterilization method can be used for quickly and efficiently sterilizing powdered particles of food, the steps are reduced, and the cost is saved.

Description

technical field [0001] The invention relates to a superheated steam sterilization equipment, which comprises a sterilization container inside which can accommodate materials to be sterilized and a steam generating device for supplying steam to the sterilization container. [0002] The invention also relates to a superheated steam sterilization method, which includes the step of sending superheated steam into the processing kettle for high temperature sterilization. Background technique [0003] For the sterilization of food powder particles, there are heat sterilization, chemical sterilization, ultraviolet sterilization, microwave sterilization, radiation irradiation sterilization, etc., because the importing country of the export product has various restrictions on the sterilization method, so heat sterilization is the current export food powder The mainstream sterilization method of particles. The current heat sterilization equipment mainly includes a sterilization contai...

Problems solved by technology

However, due to the increase of moisture and agglomeration when the powder or granular food is sterilized by the wet heat method, re-drying and crushing must be carried out after sterilization.

For those items with strong water absorption and easy water absorption, they will also be adsorbed inside the pipeline of the equipment, causing pipeline blockage and affecting normal production and operation.
