In recent days, spring tea in our city has entered the picking period. The following four preparations must be made before the spring tea is processed: 1, clean processing environment and venue Completely cleans the yard and environment of the tea processing plant, prepares a clean and clean processing environment for the new tea season, and carefully cleans the processing workshops, warehouses, and other auxiliary rooms, and wipes and cleans the walls, floors, doors and windows. Keep it clean. 2, check the tea processing equipment Make a comprehensive inspection of the status of tea processing equipment and production line, and conduct a comprehensive cleaning and cleaning; if you need to purchase equipment, you should seize the time to contact and purchase, and strive for equipment to be installed and debugged as soon as possible to avoid delays in the tea season; for last year's tea season After the maintenance of the equipment and the production line has been completed, the rust preventive oil applied to the machine should be removed after removing the covered plastic film; if the maintenance of the equipment is completed before the end of the tea season last year, a comprehensive Maintenance, seriously inspect the machine for faults and damaged parts, whether the gaps meet the requirements, if there is timely replacement and adjustment; test run on the processing equipment or the production line, carefully observe and listen whether there is not flexible operation Or abnormal noise and other phenomena, if given in a timely manner, until the normal operation, and according to the provisions of the filling of oil. To ensure that during the spring tea processing equipment and production lines can be completely put into operation. 3, preparation of tea fuel, auxiliary materials and tools According to tea processing needs, prepare enough tea making oil, liquefied petroleum gas, coal, firewood and other fuels; prepare auxiliary materials such as special oil for tea production; prepare equipment for handling teas, bamboo tea sets, etc. for tea making. 4, equipped with picking and processing personnel, do a good job training Timely provision and recruitment of a sufficient number of tea pickers and processing plant operators.

The combination and collocation of mineral nutrient elements. Among these elements, in addition to carbon, oxygen, hydrogen, nitrogen and other elements mainly exist in the form of organic matter, the other 60 kinds of elements are collectively referred to as minerals, of which 25 kinds are necessary for human nutrition.Calcium, magnesium, potassium, sodium, phosphorus, sulfur, chlorine 7 kinds of element content is more, accounting for about 60% ~ 80% of the total minerals, so called macro elements, and iron, copper, iodine, zinc, manganese, molybdenum, cobalt, chromium, tin and vanadium, silicon, nickel, fluorine, etc. 14, because there are too few, within the body content less than 0. 005%, therefore is called the trace elements.
Synonyms Dietary essential minerals; Macro- and microminerals; Electrolytes; Trace elements Definition Mineral nutrients are inorganic substances that must be ingested and absorbed in adequate amounts to satisfy a wide variety of essential metabolic and/or structural functions in the body. Mineral nutrients are sometimes categorized according to the amount required in the human diet to maintain good nutrition. Macrominerals is a general term encompassing both bulk minerals (calcium, phosphorus, magnesium) and electrolytes (sodium, potassium, chloride), which are required to be ingested by humans in amounts of hundreds of milligrams to several grams per day. Microminerals or trace elements (including iron, zinc, copper, manganese, selenium , iodine, chromium, molybdenum) are required in amounts of a few milligrams or less per day. The latter members of this group, which are required only in amounts of micrograms per day, are sometimes referred to as ultratrace elements.
