Embodiment Construction

[0035] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0036] Such as figure 1 Shown, the overall structure schematic diagram of the present invention. An intelligent microwave heating device, including a microwave generator, a waveguide system, a heating cavity, a food loading device and an intelligent microwave system. Packaged food is rapidly heated and sterilized. The frequency of the microwave source is between 890-940MHz and 2400-2500MHz, and the frequency fluctuation is less than 2MHz.

[0037] Such as figure 2 As shown, the heating chamber is divided into four parts: a preheating chamber 1 , a plurality of microwave heating chambers 2 , a constant temperature sterilization chamber 3 and a cooling chamber 4 . The whole cavity is made of stainless steel. These four parts are filled with water of different temperatures, and the packaged food passe...

Abstract

The invention relates to the technical field of food processing, and discloses a microwave heating method and an intelligent microwave system. The method comprises the following steps of through a first water circulation system, heating water in a preheating cavity to a preheat temperature, and preheating foods; through microwaves, heating water in microwave heating cavities to heating and sterilizing temperature, and heating foods; through a second water circulation system, maintaining water temperature to be the heating and sterilizing temperature, and sterilizing the foods; and through a third water circulation system, heating water in a cooling cavity to cooling temperature, and cooling the foods. The intelligent microwave system is used for controlling a food loading device to remove foods into and out of a working cavity body and move the foods in the cavity body, performing real-time monitoring on the flow speed and the water temperature of the water in the cavity body, and controlling microwave generation power. The industrialized application of microwave heating is realized through the food loading device and the intelligent microwave system, and independent water circulation systems are used, so that food heating quality is improved.

Description

technical field [0001] The invention belongs to the new technology field of food processing, and in particular relates to a microwave heating method and an intelligent microwave system. Background technique [0002] Microwave refers to electromagnetic waves with a frequency range between 300MHz and 300GHz. Microwave has been widely used in modern radar and communication technology. In addition to being used in communications, the heating properties of microwaves on dielectric materials make them a new technology for food thermal processing. The traditional thermal processing method is to heat the packaged food in hot water or steam at 121.1°C for 60-90 minutes in a high-temperature sterilizer to inactivate spoilage pathogenic bacteria and ensure the safety of the food. safety. During the heat treatment process, along with the inactivation of pathogenic bacteria, the nutritional and sensory qualities of food are reduced due to heat. In theory, increasing the sterilization...
