Famous tea fresh database installation and troubleshooting



Famous tea store obviousness often due to natural oxidation, so the natural color of dark tea, liquor color brown, flavor deterioration, thereby reducing the commercial value. Tea fresh tea library can solve the problem of natural storage in the oxide, so that spring and seasonal quarter sales, quarter after quarter have been a good price, thus raising the value of goods famous tea and corporate profits. Now famous tea cold storage installation and troubleshooting methods outlined below.

    1. The choice of keeping library

        Preservation of library library site should chose a relatively flat topography, good ventilation, temperature and humidity low, easy to tea production. Transport and storage position.

        Higher temperature requirements on the freshness of tea, cold storage temperature should be based on the inherent quality and color of tea to set the requirements. Tea in the storage period, the Treasury need to be controlled within the temperature 2-8 ℃, 5 ℃ to the best. Temperature is too low or too high will cause the tea-related changes in quality, while maintaining a certain relative humidity, it was determined to <60% as good, humidity is too large, bank Cooler easily melt the surface of frost layer, resulting in moldy tea.

    2. Fresh equipment selection model

        Volume according to the size of the Treasury and the famous tea of the fresh device to select the specific requirements of the model. Choose to pay attention to the following points.

    (L) to stage famous tea varieties such as sales and market demand factors, based on the number of decisions tea store. Database should allow adequate ventilation space, coefficient of around 0.20, as a basis to calculate the volume of the Treasury.

    (2) According to the Treasury and the famous tea fresh volume requirements to select models of refrigeration equipment. If the calculated volume of stock famous tea and use of equipment the ability to work between the two equipment manufacturers to provide the ability to work between models when the compressor power to choose a slightly larger model is better to avoid the phenomenon of small horse-drawn carts.

    (3) To use a larger production scale, product quality and stability of shape preservation equipment manufacturer products.

    3. Fresh install database

    (1) install cold storage, be sure to please experienced technical staff or directly from the factory installation.

    (2) According to the Treasury to provide, measure the required wall insulation, and foam installation.

    (3) compressor to be placed outside the appropriate location in the library; air cooler during installation to put the spring pad to prevent the nut loose; connection pipes do not bend, so as not to damage cause refrigerant leakage.

    (4) compressor voltage 380V AC, and pay attention to ground, to ensure safety.

    4. Preservation of library debugging

    In a variety of equipment, plumbing, electrical installation, check everything is correct, in accordance with the requirements of tea fresh debugging. Concrete steps are as follows (control example):

    (L) connected to power. Open the main power switch, then the power indicator light, temperature, temperature-screen display database; the instrument panel on "Measurement", "Settings" button allocated to the "set" position, then the temperature setting knob clockwise until it reaches the required temperature (the lowest temperature setting should not be less than 0 ℃), then dial the knob to the "measured" position.

    (2) refrigeration switch in the automatic position, then the work of refrigeration units, and then "dehumidifiers" switch to the automatic position. This cooling and dehumidification were involved in the control condition, the entire unit to work.

    (3) the most economic operation. In automatic mode, dehumidification function of energy consumption is larger. Tea into the library is usually 1 day, can be the most economic operation, that tea is 0-8 ℃ in temperature between the low-temperature, low humidity conditions during storage. Operation as long as the desiccant switch to "stop" of the location.

    5. SMCS maintenance

    (L) preservation libraries should be expert management, constant attention is functioning properly.

    (2) regular checks of power, prevent missing running.

    (3) cold storage refrigerator assembly of the pressure controller, when the machine breaks down and stop running, turn off the "Cooling" switch, then start troubleshooting.

    (4) regular cleaning to prevent dust blocking the wind way.

    6. Common Troubleshooting

    (L) in the hot summer, morning and evening temperature is low, the compressor can work; the noon heat, the compressor does not work. Specific features: display temperatures in excess of 8 ℃, the compressor can not start, the temperature rise. This is mainly related to the environmental temperature of the refrigeration unit. Remedy: ① Check high and low pressure refrigeration unit controller. When the suction pressure discharge pressure too high or too low, the unit will automatically stop working. If there is pressure not match, can be ruled out. ② supply voltage under normal circumstances, the control box overload relays can be reset.

    (2) The compressor does not work, libraries, temperature does not drop. Remedy: ① Check line voltage is normal, if Phase, if so, can be ruled out. ② confirm voltage too low, the control box can overload relay reset.
