Embodiment 1

[0046] The fresh noodles are processed into shapes, packed in a high-temperature-resistant composite food bag, vacuumized, sealed by a sealing machine, and packed fresh noodles are obtained.

[0047] Open the sterilization box of the fresh solid food sterilization device in advance, adjust the medium temperature sterilization chamber, set the temperature at 100°C, adjust the high temperature sterilization chamber, set the temperature at 200°C, set the conveyor belt speed to 0.1m / s, and turn on the breeze Circulation controller, when the temperature in the sterilization chamber is kept stable at 200°C, the packaged fresh noodles are added to the conveyor belt. After being transported by the conveyor belt, the fresh noodles first enter the medium-temperature sterilization chamber for preliminary preheating, and then enter the high-temperature sterilization chamber. The sterilization chamber is heated to 170°C to 180°C in an instant, and the fresh noodles after passing through the...

Embodiment 2

[0054] After cooling the steamed and matured whole-wheat steamed buns to room temperature, they are packed in high-temperature-resistant composite food bags, vacuumized, and sealed by a sealing machine to obtain packed fresh steamed buns.

[0055] Open the sterilization box of the fresh solid food sterilization device in advance, adjust the medium temperature sterilization chamber, set the temperature at 100°C, adjust the high temperature sterilization chamber, set the temperature at 250°C, set the conveyor belt speed to 0.2m / s, and turn on the breeze Circulation controller, when the temperature in the sterilization chamber is kept stable at 250°C, the packaged fresh steamed buns are added to the conveyor belt, and after being transported by the conveyor belt, the fresh steamed buns enter the sterilization chamber and are instantly heated to 220-230°C , After the fresh steamed buns passed through the sterilization chamber are cooled, the nutritional content and hygiene standard...

Abstract

The invention provides a fresh-eating solid food sterilization device and a fresh-eating solid food instantaneous sterilization method, and belongs to the technical field of food processing. The fresh-eating solid food sterilization device comprises sterilization cavities and a conveying belt. The sterilization cavities are two hollow boxes arranged in sequence. Openings are formed in the two endsof each box. The conveying belt penetrates through the two sterilization cavities through the openings. Far-infrared heating elements are mounted in the sterilization cavities. The sterilization cavities comprise an intermediate-temperature sterilization cavity anda high-temperature sterilization cavity, and the temperature of the sterilization cavity cavities is regulated and controlled between100 DEG C and 500 DEG C. The sterilization device is adopted for sterilizing fresh-eating solid food, microorganisms are killed to achieve a food preservation effect, the good organoleptic quality ofthe food is guaranteed, there is no need to add too much equipment, andoperation is convenient; the sterilization method is suitable for sterilizing the fresh-eating solid food, a preservative is thoroughly abandoned, and people can eat the convenient, safe and healthy fresh-eating solid food.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a sterilizing device for fresh solid food and an instant sterilizing method for fresh solid food. Background technique [0002] The rich nutrition in food provides a good living environment for the growth of microorganisms, and the spoilage of food is closely related to the proliferation of harmful microorganisms. The current food sterilization methods include physical sterilization technology and chemical drug method. Chemical sterilization technology has chemical residues and food safety hazards, while physical heat sterilization technology is healthier, safer and more environmentally friendly. Therefore, food heat sterilization technology is relatively more widely used. Sterilization equipment and technology for liquid food are mature, and liquid food is sterilized by direct heating or indirect heating, such as ultra-high temperature sterilization technolo...
