The Amitek ABT30A, ABT50A, and ABT100A are professional blast chillers/freezers designed for use in commercial kitchens. These appliances are crucial for rapidly cooling or freezing food, which helps to preserve its quality, extend its shelf life, and comply with food safety regulations.
Function Description
The primary function of these devices is to perform rapid chilling (blast chilling) or rapid freezing (blast freezing) of food.
- Blast Chilling: Quickly reduces the temperature of hot cooked food from +90°C to +3°C at the core in less than 90 minutes. This process inhibits bacterial growth, preserving the food's organoleptic properties (taste, texture, aroma) and nutritional value.
- Blast Freezing: Rapidly reduces the temperature of food from +90°C to -18°C at the core in less than 240 minutes. This creates micro-crystals within the food, preventing damage to cell structures and maintaining food quality upon thawing.
- Conservation Cycle: After the chilling or freezing cycle, the appliance automatically switches to a conservation mode to maintain the desired temperature (e.g., +3°C for chilled food, -18°C for frozen food).
The control panel features a digital display and intuitive buttons (START/STOP, DOWN, UP, SOFT/HARD, FREEZING) for easy operation. Different cycles can be selected based on the food type and desired outcome.

- Temperature Range:
- Blast Chilling: +90°C to +3°C
- Blast Freezing: +90°C to -18°C
- Conservation: +3°C (chilled), -18°C (frozen)
- Ambient Temperature/Humidity: Designed for operation in ambient temperatures between +15°C and +38°C with a relative humidity of 30% to 55%.
- Refrigerant: Uses environmentally friendly refrigerants (e.g., R404a, R452a).
- Construction: Stainless steel interior and exterior for hygiene and durability.
- Accessories: Includes a core probe for precise temperature measurement, adjustable shelves/grids, and a water collection tray.
Usage Features
- User-Friendly Interface: The digital control panel allows for easy selection of operating modes and monitoring of cycles. The display shows the core temperature measured by the probe.
- Core Probe: Essential for accurate temperature control. The probe must be inserted into the thickest part of the food to ensure proper chilling/freezing.
- Pre-cooling: It is recommended to pre-cool the appliance before loading food, especially for blast chilling, to optimize performance.
- Loading Capacity: Adhere to the maximum load capacity specified for each model to ensure efficient and effective chilling/freezing. Overloading can compromise performance.
- Food Placement: Arrange food on grids or trays to allow for adequate air circulation, ensuring uniform cooling. Do not block the evaporator fan.
- Cycle Selection:
- Soft Chilling/Freezing: Suitable for delicate foods, preventing surface freezing or damage.
- Hard Chilling/Freezing: For denser or larger quantities of food, ensuring rapid temperature reduction.
- Timed Cycles: Allows setting a specific duration for chilling/freezing, useful when a core probe cannot be used.
- Safety Features: Equipped with safety devices to prevent unauthorized access to moving parts and electrical components. Visual and audible alarms indicate cycle completion or malfunctions.
- Energy Efficiency: Designed to optimize energy consumption while ensuring rapid and effective chilling/freezing.
Maintenance Features
Regular maintenance is crucial for the longevity and optimal performance of the Amitek blast chiller/freezer.
- Daily Cleaning:
- Clean the interior and exterior surfaces with a soft cloth and a mild, non-abrasive detergent after each use.
- Remove and clean the grids, trays, and water collection tray.
- Ensure all surfaces are thoroughly dried to prevent water stagnation.
- Condenser Cleaning: Periodically clean the condenser (located at the rear or bottom of the unit) to remove dust and debris. This can be done with a soft brush or vacuum cleaner. A dirty condenser reduces cooling efficiency and increases energy consumption.
- Evaporator Cleaning: The evaporator fan and coils should be cleaned regularly to ensure proper airflow and prevent ice buildup.
- Door Gasket Inspection: Check the door gaskets for any signs of wear, damage, or deformation. Damaged gaskets can lead to energy loss and inefficient operation. Replace if necessary.
- Drainage System: Ensure the drainage system is clear and free of blockages to prevent water accumulation.
- Technical Checks: Periodically inspect electrical connections, refrigerant lines, and other technical components. This should ideally be performed by qualified personnel.
- Error Messages: The appliance's control panel displays error codes (e.g., Pr1 for core probe error, Pr2 for cell probe error) to indicate specific issues, facilitating troubleshooting.
- Disposal: At the end of its life cycle, the appliance must be disposed of according to local regulations for Waste Electrical and Electronic Equipment (WEEE). It should not be discarded with general household waste.
- Spare Parts: Use only original spare parts for repairs to ensure compatibility and maintain the appliance's safety and performance.
By following these guidelines, users can ensure the safe, efficient, and long-lasting operation of their Amitek blast chiller/freezer.
