Description

  The present invention relates to the field of grain storage technology, and more particularly to an energy-saving and environmentally friendly storage device for buckwheat with a long storage period.

  Soba is an annual grass family plant that has long been the main grain and forage crop in western China, adapting to cool, moist climatic conditions, drought-tolerant, salt-tolerant, and sunshine It is produced in high-cold areas and high-altitude areas.

  Soba is a functional food certified by the US FDA (Food and Drug Administration) and is not only rich in nutrition, but also lowers cholesterol, defecate detoxifies, lowers blood sugar, lowers blood lipid levels, and increases kidney function In addition, it has an antioxidant function, regulates immunity, beautifies the skin, activates cells, and regulates physiological balance. It is an unusually healthy cereal, and is highly regarded as a “cereal king” and “noble food” in developed countries in Europe and the United States.

  The “Yellow internal organs method theory” describes “poison drug attack, five grain forage, five fruit for tasting, five fortune”. That is, it is stated that, in the element that ensures the nutritional balance of the body, five grains of cereals are the basis, and the nutritive value of buckwheat is the first place of five grains. Also in ancient China, the “Hongsa Tuname” of Lee Jin-jin is cold and dry, but it is produced from the northwest plateau where the sunshine is enough, “to remove the troubles, nourish the heart and lower the blood sugar. It is described as having the effect of “energizing, increasing renal function, and beautifying the skin”.

  Currently, the most typical method for storing soba noodles is to deposit soba noodles in a granary after drying. In this method, because the buckwheat in the granary is almost dry, it can be stored in the granary for a long time, but it must pass through a drying process in advance, and the grain loses moisture by drying, so it is easily altered and broken. When it is eaten in the future, the original taste of buckwheat is lost.

  If a normal storage method is adopted, the temperature of the buckwheat is greatly influenced by the outside temperature. When the outside temperature is high, the temperature of the buckwheat also rises, and the physiological activity of the buckwheat itself and the spread of the insect moth are fast, and the shelf life of the buckwheat Short and long-term storage affects the quality of buckwheat, and chemical fumigants must be included in the buckwheat stack to control the spread of insect worms, and there are risk factors that cause buckwheat contamination. In addition, in order to reduce oxygen, it is necessary to perform airtight treatment, and the necessary amount of human resources is large, and after the airtight treatment expires, fumigation gas may leak into the surrounding environment, There is a problem of causing personal safety damage.

  In the document CN2368271Y, both the ground and the side wall of the granary are formed with a heat insulating layer that shields the outside temperature with a heat insulating material, and a refrigeration system and a conveyor belt are provided on both sides of the granary, respectively. A plurality of concave tanks and grain guide tanks are provided on the ground inside the warehouse, and an air pipe system communicating with the refrigeration system is provided in the concave tank. When a grain is accumulated in the granary, and the refrigeration system fills the granary with the absorption air from the air pipe upwards, the grain is removed when the grain is taken out. The present invention relates to an improved bulk granule in which a good grain storage and conveyance function is realized by feeding to a conveyance belt by a conveyance screw.

  In order to solve the above problems, guarantee the quality of long-term storage of buckwheat, and satisfy energy-saving requirements, a new buckwheat storage device and storage method are required.

  An object of the present invention is to provide an oat storage device that has a long storage period, is energy-saving, and is environmentally friendly with respect to conventional technical problems.

In order to achieve this purpose, the present invention adopts the following technical proposal.
In the buckwheat storage device, the side wall, the top portion, and the bottom portion of the device all have a heat insulating structure, and the heat insulating structure is divided into an inner heat insulating layer, an intermediate heat insulating layer, and an outer heat insulating layer from the inside toward the outside. The above [Heat insulation] of the present invention refers to a real heat insulation that warms in winter and insulates in summer, and is a heat insulation material or product that builds a wall or outer fence structure, and prevents heat loss in winter. In the summer, it means the ability to block external heat and maintain a stable room temperature. "Insulation structure" usually refers to the surrounding structure (including roofs, outer walls, doors and windows), which prevents heat transfer from indoors to the outdoors in winter and from outside to inside in summer. Keep the room at an appropriate temperature.

  In the present invention, heat insulation structure is installed on the side, top and bottom of the device to keep the buckwheat stored in the device from all directions, cut the heat exchange path between the inside and outside of the device, and the thermal bridge effect Therefore, it has a good energy saving effect. At the same time, in the buckwheat storage device of the present invention, the ground itself is not a heat retaining device as in the prior art, but a heat retaining layer is installed at a depth of 1.5 m from the ground, and it is still the ground in the buckwheat storage device. So you can store the buckwheat on the ground and keep it in contact with its growing soil without being isolated from the ground as in the prior art, still touching the ground and keeping the buckwheat grains more active To do. The present invention provides a three-layer insulation barrier by installing an inner insulation layer, an intermediate insulation layer, and an outer insulation layer, maintaining the temperature inside the storage device almost constant, and the shelf life of the buckwheat is almost stable in quality for 10 years. Can reach to the extent.

  In winter, when the amount of heat in the apparatus is about to pass through the three-layer heat insulation structure, the amount of internal heat is reduced by being efficiently cut off. In summer, the three-layer thermal insulation structure also blocks the transmission of solar radiation and external heat to the device, creating a comfortable environment that is warm in winter and cool in summer. In the northern part of China, the summer period is particularly short, and the period higher than the temperature of 20 ° C. is not long. Therefore, by adopting the buckwheat storage device of the present invention, the temperature of the buckwheat storage device is reduced to 1 to 2 every summer. The temperature of the buckwheat storage device can be maintained at 5 to 15 ° C. only by turning it down. At the same time, adopting the buckwheat storage device of the present invention, because of its unique heat-retaining layer setting, soba grains etc. naturally breathe and release heat, even in winter, just supply heat once or twice. Further, it is possible to realize the temperature in the buckwheat storage device at 5 to 15 ° C. without further heating.

  The outer heat insulating layer of the present invention is an injection steel wire network framework plate in which polyurethane is injected. The steel wire framework plate is formed by forming a steel wire mesh on the frame of the storage device and forms the basic shape of the device. By injecting polyurethane material onto the steel wire framework board, the load-bearing requirements of the storage device are met, and the hard polyurethane foam thermal insulation material has multiple functions, and functions such as thermal insulation, waterproofing, sound insulation, vibration reduction, etc. Also have. It has excellent thermal insulation performance and is the thermal insulation material with the lowest thermal conductivity (≦ 0.024) and the highest thermal resistance among all building materials in China at present, and the thermal conductivity is only half that of EPS foam polystyrene board. The continuous dense skin of rigid polyurethane foam and the closed pores of high strength interconnect walls close to 100% have the desired water impermeability.

  The intermediate heat insulating layer of the present invention is a heat insulating heat insulating plate, preferably a foamed polystyrene plate, a color steel plate or a hard polyurethane foam heat insulating plate, or at least two mixed plates, more preferably a hard polyurethane foam heat insulating plate. . The general name of the foamed PS plate is a foamed polystyrene board, also called a foamed board or EPS board, and foamed polystyrene beads containing a volatile liquid foaming agent are heated and pre-foamed, and then heat-molded in a mold. It is a white solid with a fine closed pore structure, and is used for heat insulation of building walls, room insulation, and composite insulation board materials. Color steel sheet coating is a product created by surface-chemical treatment of cold-rolled steel sheets and galvanized steel sheets, and then coating (rolling) or combining organic films (PVC films, etc.), then firing and curing. is there. Colored steel plates not only have high mechanical strength and are easy to form, but also have excellent decoration and corrosion resistance of coating materials, light weight, high strength, heat insulation, beautiful and durable. Have The heat insulation performance of the hard polyurethane foam insulation board is excellent, so it is the insulation material with the lowest thermal conductivity (≦ 0.024) and the highest thermal resistance among all building materials in Japan at present, and the thermal conductivity is expanded polystyrene. In the present invention, a rigid polyurethane foam heat insulating plate is preferable because it is only half of the plate.

  The inner heat retaining layer of the present invention is selected from mineral wool, ultrafine glass wool, microporous calcium silicate, or a mixture of at least two kinds of expanded perlite, and mineral wool is more preferred. Mineral wool is abbreviated as mineral cotton and has performances such as flame retardancy, fungicidal properties, and insect repellent properties, and is used as a material for sound absorption, impact resistance, and heat insulation. Mineral wool is a fluffy short and fine fiber made of mineral material, including rock wool and slag, and natural rock or metallurgical slag is melted in equipment such as cupola or tank kiln, then injection method Alternatively, it is created by centrifugation. The ultra-fine glass wool insulation material is manufactured into a fiber cotton-like size smaller than 2μm by high-temperature melting using quartz sand, feldspar, sodium silicate, boric acid, etc. as the main raw materials, and further, thermosetting resin adhesive is added and high-temperature pressure is applied.

Expanded pearlite is a white granular material with a honeycomb-like structure produced by pre-heating pearlite ore and firing and expanding instantaneously at a high temperature. The principle is that pearlite ore is crushed to form mineral sand with a certain particle size, heated rapidly by preheating firing (over 1000 ° C), and the water in the mineral sand is vaporized and softened glass It is to expand inside the mineral-containing mineral sand, and to form a non-metallic mineral product having a porous structure and having a volume expanded 10 to 30 times.

  The bottom heat insulating structure of the present invention is located under the ground, and preferably has a depth of 1.5 m or less. The heat insulation structure at the bottom of the device is installed in the basement to perform basic heat insulation. The heat insulation structure prevents the influence of the ground temperature on the buckwheat, cuts the heat exchange path between the buckwheat and the soil, and avoids the thermal bridge effect. Extend the shelf life of buckwheat. At the same time, the buckwheat storage device of the present invention is not the ground itself as a heat insulation layer as in the prior art, but a heat insulation layer is installed at a depth of 1.5 m from the ground. Is stored on the ground, so that the buckwheat is kept in contact with its growing soil without being isolated from the ground as in the prior art, still touching the ground and making the buckwheat grain more active.

The apparatus of the present invention is provided with a temperature lowering system. Furthermore, in order to lower the temperature in the buckwheat storage device, the temperature lowering system can achieve the purpose of lowering the temperature by, for example, putting cool air into the device. The temperature-decreasing system of the present invention is not particularly limited as long as it can function to lower the temperature in the storehouse. Preferably, the temperature lowering system can be installed at the bottom of the buckwheat storage device to facilitate direct temperature drop of the buckwheat grain.
The device of the present invention is provided with a reversing mechanism. The reversing mechanism is preferably a reversing mechanism for ventilation airflow. As the buckwheat grains are deposited together, the buckwheat grains still retain activity, so it inevitably undergoes metabolism, thereby releasing a certain amount of heat. The amount of heat released is accumulated in the buckwheat stack, and the more the heat goes to the center of the buckwheat stack, the higher the temperature of the buckwheat, the higher the temperature of the buckwheat. The air flow reversal mechanism is installed to reverse the amount of heat inside the center of the buckwheat stack, and the airflow near the surface of the buckwheat grain is reversed inside and circulated, so that the buckwheat grains in the buckwheat stack Maintain the temperature and the temperature of the buckwheat storage device uniformly, weaken the respiration, reduce energy consumption, retain the activity of buckwheat nutrients and extend the shelf life.

  In order to conveniently monitor the temperature of the buckwheat stack, the present invention is preferably provided with a temperature sensor for monitoring the temperature in the buckwheat stack. For example, a temperature detector may be attached to the center of the buckwheat stack, or a remote sensing temperature sensor may be installed outside, and a person skilled in the art can specifically select according to specific process conditions and process requirements. The present invention monitors the temperature at the center of the buckwheat by a temperature detector, and when the temperature in the buckwheat is higher than the set temperature, for example, higher than 15 ° C, the airflow reversing mechanism is started manually or automatically. The amount of heat at the center of the buckwheat stack is inverted to the surface, the air flow outside the barley stack is inverted to the inside, the buckwheat grain temperature in the buckwheat stack and the temperature of the buckwheat storage device are kept uniform, and the storage effect can be guaranteed.

  Another object of the present invention is to start a ventilation reversal mechanism when the temperature in the buckwheat storage device is 5 to 15 ° C. and the temperature detected by the temperature detector is higher than 15 ° C. An object of the present invention is to provide a method for storing buckwheat noodles, in which the temperature is lowered by inversion.

  Every summer, when the temperature is relatively high, the temperature lowering system at the bottom of the apparatus is started to cool the buckwheat so that the temperature in the apparatus is maintained at 5 to 15 ° C. In other seasons, it is usually not necessary to start the cooling system. When the temperature in the storage device is 5 to 15 ° C., the heat exchange amount between the inside and outside of the storehouse is very small due to the function of the heat insulating structure, so that a suitable temperature can be maintained without multiple temperature drops.

Compared with existing technologies, the present invention has the following beneficial effects.
This device can store soba noodles using low-temperature refrigeration technology, guaranteeing that the quality of soba noodles is almost stable, extend the storage period of soba noodles, and make low-temperature refrigeration technology environmentally friendly grain storage technology. So it helps to reduce the amount of chemical fumigant and prevent environmental pollution.

  By refrigerated buckwheat from all directions by the device and method of the present invention and maintaining the temperature in the storage device at 5 to 15 ° C., the quality of buckwheat is almost stable even after storage for 10 years, and the decrease in activity is 30%. Can be guaranteed not to exceed.
