Problems solved by technology

At present, the storage methods for these rice and noodle foods in daily households are still relatively simple. After buying them, they are often stored in bags, cartons or jars to prevent moisture and insects. However, the above storage containers are all airtight and airtight. , and due to the impact of the climate, especially in summer, the air is humid and the temperature is high. Therefore, it is easy to be damp or infested with insects at room temperature by using existing storage containers to store rice and noodle foods, and the storage period is short, so it is not suitable
[0003] The applicant has developed a breathable and moisture-proof container with good air permeability and can store desiccant through careful research, but the breathable and moisture-proof container has an integrated structure, which is only suitable for the storage of items with a small volume. Large moisture-proof storage requirements have the problem of inconvenient installation and transportation

preparation Embodiment 1

[0086] This example is used to illustrate the preparation of the waterproof and breathable particles provided by the present invention.

[0087] Heat 100 grams of quartz sand with an average particle diameter of 0.25mm to 50°C, then add 5 grams of liquid polyvinyl alcohol tert-butyraldehyde modified epoxy resin, stir well, then add 1 gram of polyamide curing agent, and stir evenly. The epoxy resin is coated on the surface of the quartz sand; then, cooled to room temperature, crushed and sieved to obtain the coated first aggregate particles, and calculated by weighing method, the total weight of the coated first aggregate particles As a basis, the content of the hydrophobic substance coating layer is 6% by weight.

preparation Embodiment 2

[0089] This example is used to illustrate the preparation of the waterproof and breathable particles provided by the present invention.

[0090] Heat 100 grams of ceramsite with an average particle diameter of 0.23mm to 50°C, then add 4 grams of silicone resin, stir thoroughly, then add 0.5 grams of dibutyltin dilaurate curing agent, and stir evenly to make the silicone resin Cover the surface of the quartz sand particles; then, cool to room temperature, crush and sieve to obtain the first aggregate particles of the coating, and calculate by weighing method, based on the total weight of the first aggregate particles of the coating, The content of the hydrophobic substance coating layer was 4.3% by weight.

preparation Embodiment 3

[0092] This example is used to illustrate the preparation of the waterproof and breathable particles provided by the present invention.

[0093] Mix 50 grams of quartz sand with an average particle diameter of 0.25 mm and 50 grams of glass microspheres with an average particle diameter of 0.31 mm and heat to 50 ° C. After that, add 2 grams of liquid polyurethane resin, stir well, and then add TDI trimer 0.2 grams of body curing agent, stirred evenly, so that the polyurethane resin is coated on the surface of quartz sand and glass beads; then, cooled to room temperature, crushed and sieved to obtain the first aggregate particles coated with the coating, and calculated by weighing method , based on the total weight of the film-coated first aggregate particles, the content of the coating layer of hydrophobic substances is 2.2% by weight.

Abstract

The invention provides an air-permeable moisture-proof container capable of being assembled. The air-permeable moisture-proof container capable of being assembled comprises an air-permeable moisture-proof container body and a container cover which are matched. The air-permeable moisture-proof container body comprises a bottom surface and a lateral wall, wherein the lateral wall is in a double-layer structure and comprises an inner-layer lateral wall and an outer-layer lateral wall, a hollow cavity used for containing drying agent is formed among the inner-layer lateral wall, the outer-layer lateral wall and the bottom surface, the inner-layer lateral wall is formed by inner-layer freshness preservation boards in an assembly mode, the outer-layer lateral wall is formed by outer-layer freshness preservation boards in an assembly mode, and the air-permeable moisture-proof container body is formed among the inner-layer freshness preservation boards, the outer-layer freshness preservation boards and the bottom surface in an assembly mode. The air-permeable moisture-proof container is capable of being installed on site according the scale requirements, and has a good food freshness preservation effect.

Description

technical field [0001] The invention belongs to the field of food preservation and relates to a breathable and moisture-proof container, in particular to a splicable breathable and moisture-proof container which can be assembled on site according to the required scale. Background technique [0002] With the development of society and the improvement of people's living standards, people pay more and more attention to the rationalization of diet structure. The rice and noodle foods that are eaten daily, such as rice, millet, white noodles, millet noodles, corn noodles, soybeans, mung beans and red beans, are almost A must-have staple in every household. At present, the storage methods for these rice and noodle foods in daily households are still relatively simple. After buying them, they are often stored in bags, cartons or jars to prevent moisture and insects. However, the above storage containers are all airtight and airtight. , and due to the impact of climate, especially ...
