Description
Technical field
The present invention relates to a kind of cartridge bag that can discharge ethylene gas, it has dematuration to fruits and vegetables.
Background technology
Ethylene gas is a kind of plant hormone, the fruits and vegetables after adopting of being commonly used to accelerate the ripening, but its inflammable and explosive easy polymerization directly uses inconvenience.
Ethephon (CEPHA) (2 chloroethyl phosphoric acid) is a kind of solid soluble in water, can discharge ethylene gas under alkali condition, is the postharvest fruit and vegetable material commonly used that accelerates the ripening, its molecular formula and producing shown in the following reaction equation of process of ethene (alkali is example with NaOH):
Its method of application is generally sprays and soaks.Sprinkling be with ethephon (CEPHA) be dissolved in be made in the water adopt behind the certain density solution proper device with solution atomization after spray on fruit and vegetables, but there is the problem inhomogeneous, that treating capacity is little of handling in this method.Chinese patent CN201878690U has described a kind of device that can the uniform atomizing ethephon (CEPHA) aqueous solution, and it is furnished with casing, atomizer, fan and control panel, but this device complicated operation, is difficult in the orchard worker large-scale promotion and uses.
Infusion method is that fruit that needs are accelerated the ripening and vegetables are soaked to place to dry behind the certain hour in the ethephon (CEPHA) aqueous solution and accelerate the ripening, and this method has increased treatment process, during processing between the fruits and vegetables or the collision between fruits and vegetables and the container cause the damage of fruits and vegetables easily.And be to spray or soak to accelerate the ripening all to have a certain amount of ethephon (CEPHA) residual, this affects for sale and the edible of consumer of fruits and vegetables.Chinese patent CN201830829U has described a kind of ethylene gas generator, and it is made up of ethephon (CEPHA) storage tank, alkali lye storage tank and reactor, discharges ethene thereby with pump ethephon (CEPHA) and alkali lye are mixed in reactor in proportion during use.But this device volume is bigger, and cost is higher, and complicated operation is difficult to promote on a large scale.The more important thing is the inflammable and explosive easy polymerization of ethylene gas, this device can bring bigger potential safety hazard.Some fruits and vegetables will reach the good effect of accelerating the ripening needs slowly lasting and uniform ethene processing procedure, often reaches a couple of days, and above technology all can not realize this purpose.Chinese patent CN101999402A has described a kind of slowly gel of ethene, and it mixes materials such as ethephon (CEPHA), alkali and gel, soaks certain hour before using and gel is put into the fruits and vegetables closed container carry out ethene and discharge in water.But the production of at first this gel, is difficult to each component is evenly mixed owing to gel viscosity is bigger than trouble, thereby causes the instability of quality; Secondly because the gel gas permeability is relatively poor, the ethylene gas that inner ethephon (CEPHA) produces is difficult to be diffused into gel surface, has therefore caused to discharge not exclusively; Need before reusing to be soaked in water, because the highly basic in the gel is soluble in water, and it is excessive with respect to ethephon (CEPHA), and it may be stained with on the human body or flow to the fruit and vegetable surfaces of desiring to accelerate the ripening, all be a kind of threat to human body and fruits and vegetables, therefore this technology also has bigger defective.
Some seasonal fruits and vegetables often need to accelerate the ripening more flexibly and timely processing in addition, and orchard workers more wish in packing, transport and deposit in the link and handled on a small scale by oneself, such as add ripener in packed fruits and vegetables.Chinese patent CN101715810A has described a kind of solid fruit ripener, and it is made up of ethephon (CEPHA), solid base auxiliary agent, stabilizing agent, discharges after dipping in water before the use in water.But because ethephon (CEPHA) and solid base auxiliary agent all are materials soluble in water, the apparent shortcoming of this ripener at first is that ethephon (CEPHA) and solid base auxiliary agent are partly dissolved and have caused the caking of whole ripener when dipping in water, thereby can't accomplish at the uniform velocity, discharge slowly, and inner ripener is also because caking causes discharging complete; Secondly the product described of this ripener and Chinese patent CN101999402A is the same has alkaline liquid and flow on fruit and vegetable surfaces or the human body after dipping in the water use, fruits and vegetables and human body are all had potential threat.
Therefore be badly in need of on the market a kind of easy to use, discharge the control of ethene adjustable-speed joint, use safety and the free of contamination ripener of noresidue.
