Description

Technical Field

In order to improve the drying efficiency, some drying equipment also has a vacuum pumping device. However, this device keeps the negative pressure pump running all the time, and actually the speed of evaporating water is not so fast, which will cause the equipment to run idly, not only consuming energy but also generating a lot of noise.

Specific embodiments

[0014] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation on the present utility model. In addition, the technical features involved in the following various embodiments of the present utility model can be combined with each other as long as they do not conflict with each other.

[0015] As Figure 1-2 shown:

[0016] A drying device for preparing dried Rosa roxburghii tratt fruits includes a cabinet body 1. The top of the cabinet body 1 is a drying chamber 2, the bottom is an equipment room 4, and the middle is separated by a microwave heating module 3. The drying chamber 2 is provided with a sealing door 22 (a sealing rubber strip 221 can be arranged on the matching surface between the outer periphery of the drying chamber 2 and the sealing door 22 to increase airtightness), and the equipment room 4 is provided with a dust-proof door; a plurality of pairs of slide rails 21 are symmetrically arranged on both side walls of the drying chamber 2 for installing drying baskets 211; the equipment room 4 is equipped with a control cabinet 9, an air compressor gas cylinder 6, and a vacuum pump 7. The inlet of the air compressor gas cylinder is connected to the inside of the drying chamber 2 through a connecting pipe 51, and a constant differential pressure valve 5 is connected in series on the connecting pipe 51. The outlet of the air compressor gas cylinder is connected to the vacuum pump 7 through a suction pipe 71, and a check valve 72 is connected in series on the suction pipe 71.

[0017] Working principle: Since the seeds inside the Rosa roxburghii tratt fruits need to be cut out before preparing dried Rosa roxburghii tratt fruits, there is no need to worry about the problem of thermal expansion and explosion when using microwave heating. Using microwave heating, the overall uniform heating will not result in uneven heating. Before the heating process, turn on the vacuum pump 7 to evacuate most of the gas in the air compressor gas cylinder 6 and the drying chamber 2 to make it in a sub-vacuum state. Then turn on the microwave heating module 3 to heat the Rosa roxburghii tratt fruits (the microwave heating module 3 is the same as the microwave module in a microwave oven, but with a higher power). Since it is in a sub-vacuum state, the heated moisture will quickly evaporate. When the steam in the drying chamber accumulates to a certain extent, the pressure difference with the air compressor gas cylinder 6 increases. When it increases to the fixed opening pressure difference of the constant differential pressure valve 5, the valve opens, and the air compressor gas cylinder 6 will quickly suck out the steam in the drying chamber. After the pressure difference decreases, the valve closes.

[0018] In order to ensure that the pressure in the drying chamber 2 is always lower than the atmospheric pressure, there will also be a maximum value for the pressure of the air compressor cylinder 6. For example, if the maximum pressure of the drying chamber 2 is set to 0.8 atmospheres and the opening pressure of the constant differential pressure valve 5 is 0.1 atmosphere, then the maximum pressure of the air compressor cylinder 6 shall not exceed 0.7 atmospheres. Therefore, after several suction operations, when the air pressure in the air compressor cylinder 6 reaches the maximum threshold, the vacuum pump 7 is started to suck out the steam in the air compressor cylinder 6 for the next cycle. During the suction process, the constant differential pressure valve 5 will also open automatically, so as to ensure that the vacuum degree returns to a low value. In this way, the drying chamber 2 is always in a low-pressure state, enabling the moisture of the rosa roxburghii tratt to evaporate rapidly and be discharged to complete drying, and the vacuum pump 7 only needs to work intermittently, which can greatly reduce energy consumption and noise.

[0019] For the convenience of external control, a control panel 8 is installed on the side wall of the cabinet body 1. The control panel 8 is connected to the control cabinet 9 and is used for inputting and displaying working parameters. At the same time, a pressure sensor 61 can be installed on the air cylinder. The signal is transmitted to the control cabinet 9 through the pressure sensor 61 to feedback and control the opening and closing of the vacuum pump 7. In this way, the equipment can automatically control the air extraction after startup.

[0020] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
