Problems solved by technology

When the treatment temperature is low, although the fruit matures and metabolizes slowly, it takes a long time to treat with 1-MCP. When the temperature is high, the fruit matures and metabolizes quickly, but the required treatment time is short

Embodiment 1

[0034] The vehicle-mounted 1-MCP delays fruit ripening and aging pressure swing adsorption precision processing device, including a sealable vacuum vehicle-mounted steel structure transport box 1, which adopts a special anti-external pressure design structure, and uses polyurethane foam for heat preservation. Under the vacuum degree of 0.08MPa, the box body does not produce any deformation, and a sealable box door is installed on the box body for the entry and exit of fruits; the vehicle-mounted Freon air-cooled refrigeration unit 2 and the air cooler 4 are used for fruit entry 1 The temperature of the fruit to be processed can be lowered to a sub-normal temperature of 8-10°C; the vacuum system 4 is composed of a vacuum pump, a pneumatic valve and a connecting pipeline, which provides the vacuum required for the design in 1 to promote the processed fruit. The escaping of the gas in the gap between the fruit pulp is conducive to the infiltration of 1-MCP into the pulp when the n...

Embodiment 2

[0036]In the miniature blueberry storage warehouse with a length of 8m, a width of 5.5m and a height of 3.5m, the temperature measurement and camera part consisting of a hard PVC plastic sealed box, a weather thermometer with a division of 0.1°C, an adjustable focus micro camera and an LED infrared light source is suspended on the The height of 1.5m in the middle of the main channel in the cold storage is used as a representative temperature measurement point; use the Q9 head to connect one section of the video screen cable to the adjustable focus miniature camera, and the other end to the display screen; connect the 12V1A DC power supply to power the camera and LED infrared light source; Turn on the power supply of the display frequency, obtain images on the display screen, adjust the position of the thermometer and the focal length of the camera, and obtain clear images and readings of the thermometer on the video screen; install the display screen in a place where it is conve...

Embodiment 3

[0038] The method of using the vehicle-mounted 1-MCP pressure swing adsorption precision processing device disclosed by the present invention is:

[0039] (1) Put the fruit into the transport box and quickly cool it to a sub-normal temperature of 8-10°C;

[0040] (2) The vacuum system starts to work, so that the vacuum degree of 0.08MPa is obtained in the box, so that the gas in the gap between the fruit pulp escapes;

[0041] (3) The 1-MCP releaser is automatically turned on, and the specific concentration of 1-MCP is evenly distributed in the transport box.

[0042] (4) The gas automatic control device works to produce the pressure swing adsorption (PAS) effect, and 1-MCP quickly penetrates into the pulp gap.

Abstract

The invention discloses a vehicle-mounted 1-MCP pressure swing adsorption precision processing device and an application method. The vehicle-mounted 1-MCP pressure swing adsorption precision processing device comprises a sealable vacuumizing vehicle-mounted steel structure transport case body, a semiclosed vehicle-mounted Freon air-cooled refrigeration unit, a connecting pipeline, an air cooler, a vacuum system, a pneumatic valve, a 1-MCP starting releaser, a gas automatic entering device and a microcirculation fan, wherein a sealable case door is arranged on the transport case body and is used for inlet / outlet of fruits; the refrigeration unit and the air cooler are connected with the transport case body; vacuum degree of 0.08MPa can be obtained in the case body and no oil and gas smell flows into the case body; and the vacuum system is arranged at the top of the front end of the case body and provides the vacuum degree required by design for the inside of the transport case body, so that the escape of gases from flesh clearances of treated fruits is promoted. The whole transport case body is designed according to a standard transport container, and is convenient for vehicle mounting and highway driving. The device is comprehensive in function and low in price, and is particularly suitable for popularization; and sound development of fruit and vegetable industries in China can be effectively promoted.

Description

technical field [0001] The invention relates to a vehicle-mounted 1-MCP pressure swing adsorption precision processing device and its use method, which belongs to the device invented by the integration of various advanced technologies such as a closed container, a vacuum system, 1-MCP precise release and introduction, and automatic pressure swing adsorption. Rapid batch processing of ethylene-competitive inhibitor 1-MCP before fruit storage and shipment. Background technique [0002] A series of physiological and biochemical changes will occur in postharvest ripening and senescence of climacteric fruits, such as changes in skin color, pulp hardness, fruit sugar content, acidity, and fruit flavor. , ethylene plays a pivotal role. Many research results have shown that for most climacteric fruits, when the ethylene produced by itself or in the environment accumulates to a certain amount, the respiratory intensity of the fruit will be induced to increase, and the ripening and s...
