Description

Technical Field

[0002] Fruit cake is a food made with fruit as the main raw material. It usually adopts ultra-low temperature process technology to retain the unique ingredients of the fruit without adding any pigments and edible glue. There are many types of fruit cakes. Fruit cakes in different regions may have different production methods and flavor characteristics. Drying is an important process in the processing of fruit cakes. A steam host is required in the process of drying fruit cakes. The steam host can dry the processed fruit cakes and extend the shelf life and maintain the taste and nutrition of the fruit cakes by drying the moisture in the fruit cakes.

[0003] Although traditional steam main units have the ability to dry steam, they still have some shortcomings. For example, they are not effective in discharging condensed water, which easily causes steam-water shock in the steam pipe, making it difficult to ensure the safe operation of the steam system. In addition, they lack heat recovery and moisture removal capabilities, so they can only directly discharge the moisture inside the casing and it is difficult to reuse the heat, which will reduce energy utilization and increase operating costs. Therefore, a steam main unit dedicated to drying is proposed to address the above problems. Utility Model Content

[0028] Working process: First, power on all electrical appliances and connect each appliance to an external controller. The casing 1 can provide good support and structural stability for the whole. The circulating fan 2 can provide good blowing capacity, so that the steam inside the casing 1 can be blown out more evenly to ensure the drying effect of the fruit cake. The bracket 301 in the heating system 3 can install and support the finned radiator 302. The finned radiator 302 can heat the steam. When the steam passes through the finned radiator 302, the heat is transferred to the inner wall of the base tube through convection, and then transferred to the outer wall and fins through heat conduction. Finally, the surrounding air is heated by forced convection and radiation to achieve the purpose of heating. The steam can be heated, and the setting of the wind collecting hood 303 can gather the steam to ensure that the steam can pass through the finned radiator 302. The steam control system 4 can control the steam, thereby adjusting the outlet air temperature.

The steam trap 501 can automatically remove steam condensate in the heating equipment or steam pipe without leaking steam. The steam trap 501 discharges condensate in the steam pipe through the first drain pipe 502 and the second drain pipe 504 to prevent steam-water shock in the steam pipe and ensure the safe operation of the steam system. The bypass stop valve 505 can be opened to quickly exhaust and heat up, while the check valve 503 can prevent condensate from flowing back. The heat recovery and dehumidification system 6 can provide heat recovery and dehumidification capabilities, so that the moisture inside the casing 1 can be reused as heat, thereby improving energy utilization and reducing operating costs. According to the host control The system mode is time control or humidity control mode. The host sends a control signal to open the control air valve 602 and the dehumidification fan 605, and the moisture in the casing 1 is discharged to the outside through the dehumidification outlet 604. At the same time, fresh air is added to the casing 1 through the fresh air supply port 603, so that the wind field in the casing 1 is in a balanced state. In the process of dehumidification and air supply, heat exchange is achieved through the heat exchange core 601, that is, the high-temperature and high-humidity gas in the dehumidification process is converted into low-temperature and high-humidity gas through the heat exchange core 601 and discharged into the environment. The air supply is to convert the low-temperature and low-humidity gas into medium-temperature and low-humidity gas through the heat exchange core 601 and add it to the inside of the casing 1, thereby improving energy utilization and reducing operating costs.
