In the process of adjusting the atmosphere of fruits, it is generally required that the concentration of CO2 be controlled within the range of 1 to 5%. The respiration of fruits will increase the concentration of CO2 in the reservoir. When the concentration is too high, a CO2 remover (also called a scrubber) must be used to remove the excess CO2 in the reservoir to reach the optimal range of the parameters for the gas conditioning. Now CO2 removal machines produced at home and abroad use activated carbon as an adsorbent. Activated carbon is made of wood shells or coal as raw materials, and carbonized, activated, and other processes of dry distillation have very well-developed micropores. The gas containing high CO2 is pumped into the activated carbon tank by a fan, adsorbed and saturated by air for several minutes, and then regenerated by air desorption. In this way, the desorbed CO2 gas is sent to the atmosphere. The modern CO2 removal machine uses a programmable controller PLC to automatically control adsorption and regeneration. If the remover has two activated carbon canisters, the adsorption and regeneration of the two can be alternated. The amount of CO2 adsorbed by activated carbon is a function of temperature and is proportional to the concentration of CO2. Usually 0 °C, 3% of the CO2 concentration as the standard, with its adsorption in 24 hours as the main economic and technical indicators. The selection of the carbon dioxide removal machine must meet the requirement of removing the CO2 from the entire air conditioning store. At a temperature of 0 to 2°C, most of the CO2 release from the fruit is about 3 to 10 mg/h, a The amount of CO2 released from the tonnage warehouse is 72 to 240 in 24 hours. The model can be selected based on the maximum CO2 emission. Table 2 is a list of CO2 strippers produced by the company.

(2) Removal is measured at 0°C storage temperature and CO2 concentration of 3%. Carbon dioxide removal machines generally use electronically controlled pneumatic three-way valves to control the switching of the activated carbon tank program. They need to be equipped with a small air compressor as a pneumatic source. The machine is equipped with a protection and operation timing control device and is equipped with a computer control interface. The entire air-conditioned storage room between the air-conditioning to achieve automatic continuous cycle removal operations. For this reason, similar to a refrigeration regulation station, an air conditioning regulation station is also installed in the air conditioning library. The regulation station is divided into two automatic or manual valve groups for intake and return air. The automatic valve adopts an electrically-controlled pneumatic valve to control the return air of the CO2 remover; a manual valve is used to control the intake and exhaust of the nitrogen generator. Large and medium-sized air-conditioned warehouses have long pipelines and are generally bonded by UPVC plastic pipes, with calibers between 70 and 110 。. When installing the CO2 remover, the gas pipeline should be tilted from 1 to 30 to the air conditioning warehouse to prevent the condensate from flowing back to the stripper, contaminating the activated carbon, degrading the performance, or even failing. During the long-term operation of the machine, the pneumatic valve must be actuated hundreds of thousands of times and the compressed air should be kept clean.

The name "three yellow chickens" was given by zhu yuanzhang. In the national ministry of agriculture's authoritative book, "Chinese poultry Chronicles", the first, the chicken is a family of natural grazing. Its meat is tender, delicious, rich in nutrition and enjoys a high reputation both at home and abroad. It has the characteristics of small size, "three yellow" (feather yellow, claw yellow, beaked yellow), strong survival ability, high egg production and tender meat quality.
Body feathers with yellow, neck feather are golden rooster, main wing feathers red with black, black tail feathers, hen the main wing half yellow and black, black tail feathers, hackle inclusions mottled black and gray plumage. The beak is yellow, single crown, high crown, 5 ~ 7 crown teeth. The crown and flesh are bright red, the eyelids are thin, the rainbow color is orange, the ear color is yellowish. The shin and PAWS are yellow and no feathers. Compact, well-proportioned, small and delicate, with a straight back, and a tight, rounded tail, like "yuanbao". The head is of moderate size.
Chicken is compared with mutton and beef, with high protein content and low fat content. In addition, chicken protein is rich in essential amino acids, which are very similar to the amino acid spectrum in egg milk, so it is a source of high quality protein. The protein content of the chicken is different according to the location, the skin and the skin without the skin. The order of the chicken is roughly the skin of the chicken, breast and thigh meat. Chicken skin has a lot of lipids, so you can't think of chicken with skin as a low-calorie food.
Chicken is also A good source of phosphorus, iron, copper and zinc, and is rich in vitamin B12, vitamin B6, vitamin A, vitamin D, and vitamin K.
Chicken and beef, lamb, lipid, contains more unsaturated fatty acid, linoleic acid and linolenic acid, can reduce the body of the possible adverse health effects of low density lipoprotein cholesterol.
The edible effect of three yellow cock
Chicken has a high digestibility and is easily absorbed by the body. It has the effect of enhancing physical strength and strengthening the body.
Modern society is busy everyday, often in sub-healthy white collar better eat a few more, to enhance immunity, reduce the disease probability. Chicken with temperature in the qi, tonify deficiency repair essence filling pulp, benefit and loss of function, used in the treatment of consumptive emaciated, virtual food less, diarrhea dizziness, palpitation, irregular periods, less postpartum milk, diabetes, edema, and other symptoms.
Can alleviate the symptom such as frequent urination, deafness, and lack of precision due to insufficiency of kidney.
It has anti - oxidation and certain detoxification. It has a good effect on improving the function of the mind and promoting the development of children's intelligence.
Taboo on the consumption of three yellow chickens
People with cold fever, excessive internal fire, severe phlegm, obesity, people with swelling of the fever, high blood pressure, high blood lipids, cholecystitis and cholelithiasis.
Chicken sexual temperature, help fire, liver Yang and oral erosion, skin swelling, stool is not suitable for food.
The patient of arteriosclerosis, coronary heart disease and high blood fat do not drink chicken soup.
Cold with headache, lack of energy, hot people avoid chicken, chicken soup.
Do not eat when taking iron preparation.
The abundant protein can aggravate the kidney burden, so people with kidney disease should eat as little as possible, especially the uremia patient, should fast.
