Hot air freezing & drying system

The principle of freezing

Products are placed in aluminum trays with lids and placed on heat exchanger plates of contact freezers. Heat exchange takes place directly from the product through the tray to the heat exchanger plates. Thanks to the hydraulic cylinder system, it is possible to adjust the heat exchanger plates to have good contact with the two sides of the product. Simultaneous heat transfer occurs on both sides of the tray, resulting in short freezing times.

Exceptional Features

  • Suitable for frozen seafood and food in block or semi IQF form.
  • Designed and manufactured in accordance with HACCP / FDA standards.
  • Fast, effective freezing and product quality assurance.
  • The cabinet surface is made of stainless steel.
  • Insulated with 150mm thick Polyurethane foam, density 43kg / m³.
  • Hydraulic cylinder system lifts high quality heat exchangers. Ensures easy entry and exit as well as even contact between the heat exchanger plates and the freezer trays.
  • Extruded aluminum heat exchanger panels are specialized in food processing technology.

  • Operation, cleaning as well as maintenance are very easy and simple.


  • Insulate the freezer room with a 125 mm thick assembled PU panel, inside and outside the tolt color bond coating.
  • The floor of the room has a slope towards the middle drain, which is convenient for spraying water to clean and defrost the indoor unit. The freezer door has enough size for workers to access and maintain and sanitize equipment.
  • The actuator has an automatic tape tensioning mechanism which is able to avoid the tape being too stretchy or too loose due to the temperature elasticity of the tape.
  • The conveyor support frame is lined with plastic bars, ensuring limited sliding friction with the conveyor, operating in high efficiency and having a long service life and meeting food hygiene requirements.
  • The airflow distribution system is properly arranged, the distance of the blow slots is far enough that the two airways are not affected by friction and it is easy to create a COANDA effect on the product surface. This means that the efficiency of cold transfer from the air to the product is optimal, with a short freezing time and reduced product loss.
  • Hinge-style windshields facilitate opening and closing each cleaning shift.
  • Squirrel cage type indoor fan creates high wind pressure, stainless steel and dynamically balanced propeller, the suction line of the fan has a curved profile for the highest efficiency and energy saving, the type capable of operating in Deep cold environment and watering outside.
  • Hot-dip galvanized steel tubes and wings with radiator fins of the indoor unit are sparse enough to last 16 hours or more. New commune rock.

Electric lighting system

For businesses that have factories, factories and warehouses, the investment and installation of appropriate lighting systems is an important issue. This not only helps to cut energy costs but also creates a comfortable, safe, and productive working environment.

In the design and construction of lighting electrical buildings, the most important issue to consider is to meet the requirements of illuminance and the effectiveness of lighting for vision. In addition to the illuminance, the effectiveness of lighting also depends on the luminous flux, the color of the light, the reasonable choice of the lampshade, the lighting arrangement while ensuring the technical economy and the aesthetic of the situation.

1. Requirements in design and construction of lighting system for factories.

  • Be sure to illuminate the work area to the illuminance on the work surface. Also ensure the color rendering index of the lamp. Meet Vietnamese standard TCVN 7114-1: 2008.
  • Meet power density and use energy most efficiently. Meet QCVN 09: 2013 / BXD National technical standards.
  • Lighting equipment must be safe, economical and friendly with the environment. Products with high performance, guaranteed quality suitable for many spaces. The device must ensure lighting even in harsh environments.
  • Use products with a wide temperature range. Ensure true reflection of the color of the object illuminated by the light.
  • Illuminated space must absolutely limit glare. In some working objects, the reflected rays are also quite strong and direct, so when arranging the lamps, pay attention to avoid this phenomenon.
  • Create the right light direction, not obscured.
  • Reduce the number of maintenance and repair times, affecting production.

Just based on the lighting design criteria in the standard factory lighting, customers will get the light design ideas for their lighting spaces.

2. Choose the right light for factory lighting

Depending on the nature and requirements of the job and factory characteristics, the following lamps can be selected:

chieu-sang-nha-xuong-14đèn led đa năng Potechđèn LED pha Potechđèn led tuýp công nghiệp
Suitable for workshops with a lot of dust (such as wood industry), storage.Suitable for work that requires high color temperature and color renderingSuitable for factories with harsh environments.Suitable for painting, garment, electronics room
