How to adjust the temperature of the shelves in the fresh food area

source：dzoneshop.com  |  Release time：2025年11月04日
      The shelves in the fresh food area are mainly regulated by integrated refrigeration systems or environmental temperature control devices, with the core being to maintain the low-temperature environment required for fresh food preservation.
Common temperature regulation methods
      Built in refrigeration unit adjustment: The shelf is equipped with a compressor refrigeration system, which sets the target temperature through a temperature controller (such as 0-4 ℃ refrigeration, -18 ℃ freezing), and the unit automatically starts and stops to maintain temperature stability.
      Cold air circulation regulation: connected to the supermarket refrigeration system, cold air is evenly blown through the internal air ducts of the shelves, and the size of the air outlet is adjusted to control the wind speed and temperature, adapting to different preservation needs such as fruits, vegetables, and fresh meat.
      Thermal insulation structure assisted temperature control: The shelves are made of insulation boards, combined with sealed doors or transparent covers to reduce air loss and temperature fluctuations, especially suitable for frozen shelves.
      Layered temperature control design: Multi layer shelves can achieve independent temperature adjustment of different layers, such as upper layer refrigerated fruits and vegetables, lower layer frozen meat, meeting diverse fresh storage needs.
