Fruits and vegetables controlled atmosphere storage Technical Specifications1 ScopeThis standard specifies the fruits and vegetables controlled atmosphere storage procedures and technology. This standard applies to all kinds of fruits and vegetables, especially for climacteric fruits, vegetables, such as apples, pears, bananas and garlic sprouts such as controlled atmosphere storage. Type 2 atmosphere storage Atmosphere storage can be divided into two types. 2.1 Type Ⅰ Reducing the oxygen content, increased carbon dioxide content, but the content of oxygen and carbon dioxide and 21% (volume fraction). 2.2 Type Ⅱ Reducing the oxygen content, increased carbon dioxide levels, the sum of oxygen and carbon dioxide content of less than 21% (volume fraction). According to product type and adjust the gas composition into account the following factors. --- Fruits and sensitivity to high concentrations of carbon dioxide hypoxia; --- Maturity; --- Storage time.3 atmosphere storage methodAtmosphere storage There are three main methods. a) storage products in the storage device from time to time with special equipment, special equipment used for preparing the gas composition different from normal gas group Combined and allowed to keep the concentration of oxygen and carbon dioxide stored within a limited range; b) storage products in the set with a good breathable silicone rubber membrane production than the large tent bag or storage; c) short-term storage of products of high carbon dioxide treatment.4 controlled atmosphere storage library4.1 Capacity Air conditioned storage capacity ships from dozens of tons of the first 1,000 tons. 4.2 tightness Atmosphere storage rooms should reach a certain level of airtight to maintain the stability of the gas component library. 4.2.1 Minimum gas density Low density gas atmosphere storage rooms should meet under the most stringent operating conditions to use. 4.2.2 construction Air conditioned building structure should have good insulation, air tightness and security. Fabricated cold storage walls, floors and ceilings should be adopted Color material sandwich steel, aluminum, fiberglass reinforced polyester resin, amide resin, epoxy resin or the like. Brick structure for the gas barrier due Vapor barrier function and air tightness, the foundation should be stable, without precipitation, deformation. Storage room with a heat-insulating door seals should be installed on the door observation window And enter the door of the storage room. Check the settings stored in the upper window between its position should be higher than the height of stacking storage products in order to facilitate the passage of the Window into the upper storage products, check stored products, evaporators and refrigeration equipment condition. Airtight material should have the following characteristics. ---airtight; --- Not release odors or toxic substances; --- Waterproof, anti-bacterial; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23244-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23244-2009_English as soon as possible, and keep you informed of the progress.
