How the choose and buy is compound air air lasts packer
Compound air air lasts the equipment that pack is vegetables of fruit of our country food lasts the high-tech product with brand-new domain, this product is in maintain food fruit vegetables the respect such as original gust and nutrient value, have distinct advantage. But, the manufacturing company of this kinds of a few equipment, below the circumstance that did not master core technology, through the model copy makes unqualified product, use method of false conduct propaganda, false and inferior device the sale gives an user, last accordingly as a result of short of the effect, make many users call greatly be duped, thinking air air lasts then is a kind of cogged technology. Visit lasts to damaged compound air air badly the credit of packer industry, the healthy progress that gives this the industry caused huge negative effect.
Face this kind of situation, take the lead in in our country the success of research and development, Suzhou Sen Ruibao that owns patent of 5 countries technology is bright Lu Jinyan of general manager of equipment limited company is advanced the engineer feels to this state regret and but. Lu Jinyan's senior engineer thinks, through increasing compound air air to last only technical conduct propaganda is mixed promotion strength, let broad user master the method that differentiates qualification and rejected product, establish mandatory national standard or occupation standard, ability from go up at all keep within limits is illegal air air lasts behavior of user of equipment manufacturer deceit, ability promotes the healthy development of this group course of study.
One, compound MAP packs key of lasted 2 old techniques
Compound air air lasts pack also say aeriform displacement is packed, MAP is called to pack on international (Packing of of Tmosphere of A of M Odified ) . Compound air air lasts the principle that pack is to use 2 ～ 4 kinds of gas, undertake deserving to compare according to the character of food, mix, undertake displacement to packing box or the air inside the bag that pack, the change packs a box or pack the external environment of the food inside bag, restrain microbial (include a bacterium) grow progenitive, slow down is fresh the metabolic speed of fruit vegetables, lengthen food fruit vegetables thereby last period, keep in storage and goods shelves period. Use compound air air to last pack, can the mouthfeel taste with original vegetables of fruit of food of better land reservation and nutrient material.
Eligible compound air air lasts packer, the technical index that has 2 big keys must accord with corresponding requirement, mark of this 2 thumb is respectively: It is aeriform replacement rate wants tall, 2 it is gas blends precision error rate to want low. Compound air air lasts the quality of the equipment that pack is eligible, need is judged with these 2 crucial index. Air air lasts gas is general by carbon dioxide (CO2) , nitrogen (N2) , oxygen (O2) reach composition of a few special type gas. Carbon dioxide is had restrain most corrupt bacterium and mould to grow progenitive, slow down is fresh the action of speed of fruit vegetable metabolism, it is to last the composition of main curb bacterium in gas; Oxygen is had restrain bacterium of oxygen of most be disgusted with to grow, maintain salmon lustre and maintain fresh fruit vegetables to require the oxygen breath, action that holds delicacy to spend; Nitrogen is inert gase, do not act well with food, regard fill as gas, as compound as carbon dioxide, oxygen and composition of special type gas last gas. Vegetables of different provision, fruit, what need last aeriform composition and proportion are not same also.
