Technical Field

[0001] The invention relates to the field of food processing and is a superheated steam egg steaming device based on water-heat cycle. Background Art

[0002] The superheated steam egg steaming equipment based on water-heat cycle is a kind of equipment that uses superheated steam to steam and cook poultry eggs. Superheated steam technology refers to heating the liquid until it is completely evaporated into saturated steam, and then continuing to heat it to obtain a drier steam. Its temperature is higher than the saturation temperature corresponding to its pressure. The superheated steam egg steaming equipment based on water-heat cycle converts water into water vapor through a heating tube and enters the superheated steam egg steaming chamber, and is heated to superheated steam under the action of an infrared heating device. Superheated steam has better steam decomposition rate, gas composition, higher gas temperature and heat capacity, and higher thermal efficiency. As an agricultural product processing technology, it has been widely used and studied.

[0003] Chinese patent number CN206284311U is a steamed egg device invented by Wang Lu et al. The main part of the device is a cylindrical tank supported by a support rod. It has the advantages of convenient steaming operation, labor saving, and good sealing effect, but it is complex to manufacture, has high cost, large volume, waste of space, and low energy utilization.

[0004] The egg steamer designed by Chen Bangqi and others with Chinese patent number CN202145858U has a main body of a box with a steam port outside the box. Hot steam is introduced through the steam port and enters the box for steaming eggs. When the steam cools down or the eggs are cooked, the steam outlet is opened to release the steam in the box. It has the advantages of uniform heating and convenient operation, but there are problems such as large steam usage, high energy consumption and long processing time.

[0005] Chinese patent number CN213155398U Zheng Wenwen et al. designed a multi-station egg steamer, which drives the product to be heated more evenly in the egg steamer through the rotation of the placement box, and better guarantees the qualified rate of the product. However, the egg steamer has problems such as small processing volume, space waste and high energy consumption. Summary of the invention

[0006] A superheated steam egg steaming device based on water-heat cycle, characterized in that the egg steaming process is divided into three stages: 1. preheating stage 2. superheated steam stage 3. cooling and heat energy recovery stage. The technical problem to be solved by the present invention is that the traditional steam egg steaming method has high energy consumption, low heat energy utilization rate, high processing cost, low resource circulation rate and low space utilization rate.

[0007] The purpose of the present invention is to solve the problem of high energy consumption of existing egg steaming equipment. A superheated steam egg steaming technology is disclosed, which includes an electric heating tube (5), an infrared heating element (6) and a water tank (26). The electric heating tube (5) heats the water in the water tank (13) to form water vapor, and the water vapor enters the superheated steam egg steaming chamber through a mesh port, and is heated by the infrared heating element (6) to increase the temperature to form superheated steam, and the eggs on the tray (24) in the material vehicle are heated by superheated steam to ensure the calorific value and uniformity of the superheated steam. The system uses superheated steam as a heating medium. Compared with traditional saturated steam, superheated steam has better steam decomposition rate, gas composition, higher gas temperature and heat capacity, and higher heat transfer efficiency, and can heat the eggs to maturity faster, thereby improving the heating rate.

[0008] The purpose of the present invention is to solve the problem of low water recycling rate in existing egg steaming equipment. A water recycling system is disclosed, which includes a steam outlet, a condensed water recovery tank (26), a water tank (13), etc. In the egg steaming preheating chamber, the superheated steam egg steaming chamber, and the cooling and waste heat recovery chamber, a condensed water recovery tank (26) is installed at the bottom. These devices collect condensed water generated during the egg steaming process, and flow into the water tank along the surface of the chamber to be transported back to the water tank (13) for reuse. The system aims to save water resources by recycling and reusing the condensed water generated during the egg steaming process. Such a design reduces the demand for external water resources, improves the water utilization efficiency, and conforms to the concept of sustainable development.

[0009] The purpose of the present invention is to solve the problem of low thermal energy utilization rate of existing egg steaming equipment and disclose a heat recycling system including an electric heating tube (5), an infrared heating element (6), a hot air ventilation chamber (28), etc. In the cooling and waste heat recovery chamber, a large amount of heat energy is released during the cooling process after steaming the eggs. The system transmits this heat energy to the preheating chamber through the louver fan (large) (7) pipeline and the louver fan (small) (4) for preheating the next batch of eggs. The heat recycling system improves energy utilization efficiency by recovering the waste heat generated during the egg steaming process, thereby improving energy utilization rate.
