Description

Technical Field

[0001] The present invention relates to the technical field of preservative production, and in particular to 1-MCP preservative production equipment and a production method suitable for chili peppers. Background Art

[0002] Chili peppers are an important vegetable in my country, possessing significant economic value. A nutritious and popular fruit and vegetable, chili peppers are cultivated worldwide. Ethylene is an organic compound produced by all plants and some microorganisms that influences plant physiology and biochemistry. As a plant hormone, ethylene plays a role in many aspects of plant growth and aging, and is physiologically active even at very low concentrations (less than 0.1 mg / kg). Ethylene released during storage accelerates ripening and senescence, leading to a decrease in nutrients and quality. Therefore, controlling ethylene production can effectively mitigate its effects on chili pepper storage. Research results showed that peppers treated with 1-MCP had a significantly higher commercial yield than controls, and chlorophyll degradation, chlorosis, and softening processes were slowed. Furthermore, ethylene release was lower in 1-MCP-treated peppers than in controls, indicating that 1-MCP effectively reduces ethylene biosynthesis, thereby delaying senescence and increasing commercial yield. Currently, there are many methods for preparing 1-MCP. A common method is to use cyclopropene and vinyl chloride to carry out a catalytic reaction to obtain 1-MCP gas, which is then subsequently separated. There are many separation methods, and condensation is a common separation method. However, current condensation equipment can only achieve static separation, that is, droplets adhere to the inner wall of the condenser tube and fall freely, resulting in low collection efficiency. Based on this, the present invention proposes a 1-MCP preservative production device and production method, which can dynamically collect condensed droplets, increase their falling speed, and reduce the amount of droplets adhering to the inner wall of the pipe.

The condenser 19 is fixed by the fixed shaft 33. The motor 21 works to rotate the rotating shaft 15 and the driving screw 22, and the cleaning platform 23 can move along the condenser 19 to remove the dirt attached to the outside of the condenser 19; when the driving screw 22 rotates, it drives the rotating plate 38 to rotate, and the contact arc portion 39 can push the contact ball portion 36 in a contact manner, that is, the telescopic shaft 35 is repeatedly extended and retracted to impact the inside of the condenser 19. A rubber buffer pad can be set at the end of the telescopic shaft 35 to reduce noise; the condenser 19 generates vibration, which can accelerate the droplets attached to the inner wall to fall.

The condenser 19 can be repeatedly lifted by the lifting electric cylinder 12, and the residual droplets attached to the inner wall of the condenser 19 can be thrown off by the falling inertia; subsequently, the condenser 19 can be fixed again by the fixed shaft 33.
