Description

Technical Field

[0001] The utility model relates to the field of fruit and vegetable crisp slice processing, in particular to a fruit and vegetable crisp slice processing device. Background Art

[0002] Fruit and vegetable chips are a general term for fruit chips and vegetable chips. They are made of fruits and vegetables as the main raw materials and are produced through vacuum dehydration and other processes. When slicing and dehydrating, vacuum dryers are mainly used for dehydration. When the existing steam vacuum dryer processes fruit and vegetable chips, the steam pipe 2 transports high-pressure and high-temperature steam to the vacuum dryer 1 for heating (such as Figure 3 As shown in the figure, the high-temperature steam evaporates the moisture on the surface of the material, and after adsorption by the vacuum pump 4, the vapor treated with moisture inside the vacuum dryer 1 is extracted and sent to the water separator 6 for gas-liquid separation. However, due to the internal heating of the vacuum dryer 1, some steam condenses and falls to the bottom and accumulates. In order to ensure the drying effect of the vacuum dryer 1, the operator will regularly open the sewage control valve at the bottom of the vacuum dryer 1 to empty the liquid. Manual operation is not only troublesome, but the discharged liquid also pollutes the surrounding environment. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a fruit and vegetable crisp chip processing device.

The collector is provided with an automatic drainage system.

[0006] Further optionally, the connection between the drain pipe and the connecting pipe is arranged to be inclined, and the inclination direction of the connection is the same as the flow direction of the liquid in the connecting pipe.

[0007] Further optionally, the collector includes a liquid collecting box arranged at the bottom end of the vacuum dryer, the top of the liquid collecting box is provided with a V-shaped cover body, and a plurality of liquid collecting ports are opened on the upper part of the V-shaped cover body.

[0010] Compared with the existing technology, the beneficial effects of the present invention are: the present invention prevents rainwater from entering the cable trench through the gaps between the cover plates by arranging a frame-shaped guide trough frame between the cover plates of the cable trench, thereby greatly reducing the accumulation of rainwater in the cable trench and fundamentally solving the problem of artificial drainage.

[0015] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 、 2 As shown, a fruit and vegetable crisp processing device includes a vacuum dryer 1 for drying and heating the fruit and vegetable crisps, and a buffer tank 3, a vacuum pump 4 and a water separator 6 connected by pipelines. A collector 7 is provided at the lower end of the vacuum dryer 1. The collector 7 is used to collect liquid falling from the vacuum dryer 1 to prevent the collected liquid from secondary evaporation and affecting the drying effect of the fruit and vegetable crisps. The bottom of the collector 7 is connected and fixed to the connecting pipe 5 connected between the vacuum pump 4 and the water separator 6 through a drain pipe 10. The collector 7 is provided with an automatic drainage system.

[0017] The connection between the drain pipe 10 and the connecting pipe 5 is set at an angle, and the inclination direction of the connection is the same as the flow direction of the liquid in the connecting pipe 5. When the connecting pipe 5 transports gas, it will quickly pass through the inclined drain pipe 10, and a negative pressure will be generated inside the inclined drain pipe 10 through the siphon principle, so that the drain pipe 10 has a suction effect on the liquid in the collector 7, thereby improving the liquid discharge efficiency.

[0018] The collector 7 includes a liquid collecting box arranged at the bottom end of the vacuum dryer 1. The top of the liquid collecting box is provided with a V-shaped cover 8. The V-shaped cover 8 has the function of receiving liquid, so that the collected liquid can quickly enter the interior of the collector 7. A plurality of liquid collecting ports 9 are opened on the upper part of the V-shaped cover 8.

[0019] The automatic drainage system includes a PLC controller 12, which is electrically connected to a control valve 11 installed on the drainage pipe 10. The PLC controller 12 is electrically connected to a liquid level gauge 13 installed on the side of the collector 7. The liquid discharge inside the collector 7 is automatically controlled by the liquid level, making the operation more convenient and quick.

[0020] The liquid level gauge 13 is located at the lower portion of the V-shaped cover 8 .

[0021] The implementation principle of the fruit and vegetable chip processing device in the embodiment of the present application is as follows:

[0022] Place the sliced fruits and vegetables into the vacuum dryer 1, open the shut-off valve of the steam pipe 2, and high-pressure and high-temperature steam is transported into the vacuum dryer 1 through the steam pipe 2 to dry and heat the fruit and vegetable slices. At the same time, the vacuum pump 4 is started, and the vacuum pump 4 absorbs the water vapor generated by the drying process in the vacuum dryer 1 through the buffer tank 3 and transports it to the water separator 6. The condensed liquid in the water separator 6 falls by its own gravity, while the gas is discharged from the gas pipe at the top of the water separator 6 to achieve gas-liquid separation.

[0023] When the steam inside the vacuum dryer 1 condenses and falls and gathers at the bottom, it will fall to the upper part of the V-shaped cover 8 of the collector 7 for concentration, and enter the inside of the collector 7 through multiple liquid collection ports 9. When the liquid level reaches the liquid level gauge 13 of the collector 7, the liquid level gauge 13 transmits the liquid level signal to the PLC controller 12. The PLC controller 12 controls the control valve 11 to open the drain pipe 10, and the PLC controller 12 has a built-in delay device to delay the drainage for 2 minutes. After the set delay period is reached, the PLC controller 12 controls the closing of the control valve 11. The liquid in the collector 7 is discharged to the connecting pipe 5 through the drain pipe 10 and enters the water separator 6 for collection, thereby realizing the collection of water resources to avoid waste. At the same time, the liquid does not require human operation and the degree of automation is high.

[0024] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
