Possibility of confined poultry house Before fumigation in a poultry house, the poultry house must be inspected for hermeticity. Glass shall be placed on windows and doors without glass or glass imperfections. If there are gaps, newspapers or tapes should be affixed to prevent leakage. Disinfection time should be more than 24 hours, if not urgently used, it can be sealed for 2 weeks. The containers for the liquid chemicals should be corrosion-resistant and have a large volume. The potassium permanganate and the formalin are corrosive. After the mixing, the reaction is violent, and the heat is released. Generally, it can last for 10-30 minutes. Therefore, the containers for containing the drugs should be sufficient. Large and corrosion resistant. With other disinfection methods, formaldehyde can only sterilize the surface of the object, so mechanical cleaning and spray disinfection should be performed before fumigation, so that the disinfection effect will be better. To provide higher temperature and humidity, the normal temperature should not be lower than 18°C, and the relative humidity should be 60%-80%. It should not be lower than 60%. When the temperature is 26°C and the relative humidity is above 80%, the disinfection effect is best. Dosage, concentration and proportion of the drug should be appropriate. Normally, 30 ml of formalin, 15 g of potassium permanganate, and 15 ml of normal water are used per cubic meter. Pay attention to safe operation, first pour water into a ceramic or enamel container, then add potassium permanganate, stir evenly, then add formalin, and the person will leave and seal the poultry house. The container should be as close to the door as possible so that the operator can evacuate quickly. The operator must avoid formaldehyde contact with the skin and must be left empty when disinfected. After disinfection, the smell of formaldehyde in the poultry house is relatively strong and irritating after the disinfecting gas is disinfected. Therefore, the doors and windows of the poultry house should be opened, ventilation should be performed for more than 2 days, and the formaldehyde gas should be completely used before being completely dissipated. When it is urgently needed, ammonia can be used to neutralize formaldehyde. Method: Use 5 grams of ammonium chloride per cubic meter of space, 10 grams of quick lime, and 10 milliliters of hot water at 75°C. Mix and put in the poultry house. After 30 minutes, open the doors and windows of poultry houses and ventilate for 30-60 minutes.
HÅjicha is a Japanese green tea. It is distinctive from other Japanese green teas because it is roasted in a porcelain pot over charcoal, whereas most Japanese teas are steamed. The tea is fired at a high temperature, altering the leaf color tints from green to reddish brown. The process was first performed in Kyoto, Japan, in the 1920s and its popularity persists today.
Hojicha is often made from bancha ("common tea"),tea from the last harvest of the season; however, other varieties of HÅjicha also exist, including a variety made from sencha, and kukicha, tea made from the twigs of the tea plant rather than the leaves.
HÅjicha infusions have a light- to reddish-brown appearance and are less astringent due to losing catechins during the high-temperature roasting process.The roasted flavors are extracted and dominate this tea: the roasting replaces the vegetative tones of other varieties of Japanese green tea with a toasty, slightly caramel-like flavor. The roasting process used to make HÅjicha also lowers the amount of caffeine in the tea.Because of its mildness, HÅjicha is a popular tea to serve during the evening meal or after, before going to sleep, and even preferred for children and the elderly.
