Description

[0001] SHORT-TERM STORAGE FARMHOUSE FOR FRESH RED PEPPER [0002]

The present invention relates to a farm-type red pepper short-term storage device, and more particularly, to a farm-type red pepper short storage device capable of reducing decay rate and drying efficiency before dry red pepper production in a farmhouse without a refrigerator for storing red pepper.

Consumption of domestic red pepper powder is 2.0 - 2.5kg per capita per capita, which is 40 to 100 times higher than that of overseas, compared with 200g of major pepper consumers, 50g of USA and 20g of Japan. Produced in Korea, about 90% of red pepper is produced with dried red pepper and used for kimchi seasoning, red pepper paste, processed products.

The agricultural standard of dry red pepper (dried red pepper) is 15% or less moisture, and it is said that it has good gloss with reddish or crimson color. It is a method of producing dry red pepper, natural drying by drying in the sun, hot air drying by hot wind, In 2003, a study on the red pepper treatment plant that can produce high quality red pepper powder products was started in order to protect the red pepper cultivators from the farm and to increase the competitiveness of the domestic red pepper industry. This installation is being operated. The red pepper processing plant produces high quality red pepper powder by storing the red pepper harvested in the red pepper cultivation farm with the low temperature storage, the raw red pepper raw material washing, the continuous large size drying facility and the advanced red pepper grinding facility. Generally, post-harvest management of agricultural products is important, since quality is deteriorated due to post-harvest physiological activities. Therefore, in order to maintain freshness and safety, it should be collected quickly after harvesting and managed as a low-temperature distribution system. Especially, the physiological effect after harvesting causes the respiratory physiology, ethylene production, tissue softening, color change, etc., which is consumed by the self-storing nutrients at the time of harvest. Therefore, curing, precooling, have. The physiological characteristics of pepper after harvest are unqualified type which does not show breathing soaring phenomenon that the quality is lowered due to rapid increase of respiration after harvest. The ethylene production amount is not significantly influenced by other vegetables, In the water. In order to maintain the quality of red pepper, it can be stored at 8 ~ 10 ℃ for 2 ~ 3 weeks, and low temperature failure occurs at lower temperature. However, domestic red pepper harvest is concentrated in harvest from mid - August to late October, depending on the area. In addition, the company stopped buying red peppers in the rainy season, and the sugar content of red pepper converted to dry matter was more than 20%.

The harvested red pepper is forcibly dried in hot farming drying in some farmhouses during the period of stopping the purchase of raw materials in the red pepper general treatment plant, or stored in a place where it can be avoided and then dried or bought. That is, in the case of a red pepper treated with a large amount of red pepper, when the green pepper is not able to be put into the low temperature warehouse due to the rainy season and the increase of the yield, a storage means which does not cause a deterioration of the red pepper quality temporarily is needed.

Especially, more than 90% of red pepper is prepared with dried red pepper. Therefore, unlike other vegetables, reduction of moisture by evaporation is not a problem, and a storage method for reducing the decay rate is required.

As an example of the prior art relating to the storage of agricultural products, Korean Patent Laid-Open Publication No. 10-2012-0055425 (published on May 21, 2012) discloses a method of uniformly diffusing air introduced by a blower into the inside of a body part, There is provided a container for storing agricultural products, characterized in that corruption is prevented and freshness can be improved. In this prior art, there is a conventional art in which agricultural products are stored inside and a body portion having an air diffusion hole on a bottom surface is supported on one side of the support portion for supporting a lower end portion of the body portion, And a protrusion formed on a bottom surface of the main body and having an air injection hole formed at an upper end and a side surface to inject air introduced through the air diffusion hole into gaps between agricultural products, And the air is uniformly diffused into the inside of the body part to store agricultural products.

On the other hand, Korean Patent No. 10-1222758 (Announcement: Feb. 23, 2013) discloses a bag for storing agricultural products. BACKGROUND ART [0002] A bag for storing agricultural products according to the related art is a bag for storing agricultural products which can easily maintain a stored state by preventing corruption of onions stored by increasing air permeability. The bag has a plurality of open pores And a shape retaining member formed on the main body to prevent the shape of the main body from being disturbed by the stored matter stored in the main body.

However, the above-described conventional techniques are not general agricultural products storage for red pepper storage for the production of dry red pepper. Therefore, there is a problem that red pepper is easily decayed when storing red pepper with high sugar and moisture content.
