Commercial refrigerated food sample storage cabinet (sample retention cabinet)

Guide to Application, Quality, Maintenance and Energy & Cost Saving of Commercial Refrigerated Fresh-keeping Sample Cabinet

I. Application Scenarios

 Canteens of schools and kindergartens

 Canteens of enterprises, institutions and government agencies

 Hotels, restaurants and central kitchens

 Canteens of hospitals and nursing homes

 Catering companies and group meal enterprises

Key Points for Compliance Use

 Sample retention time: It is recommended to be no less than 48 hours (implemented in accordance with local market supervision requirements)

 Sample retention temperature: The temperature of refrigerated sample cabinet should be stably maintained at 0～4℃

 Sample retention weight: No less than 100g per serving to avoid affecting testing due to insufficient quantity

 Containers: Use special covered sample boxes that are corrosion-resistant and easy to clean

 Marking information: Each sample shall be marked with

 Dish name

 Sample retention time and date

 Sampler/window

 Placement method:

 Place in layers to avoid extrusion

 Separate raw and cooked food, meat and vegetarian food

 Store sample food separately from other ingredients

II. Quality Points

1. Refrigeration and Temperature Performance

 Reliable compressor brand with stable operation and low noise

 The measured temperature can be stably maintained at 0～4℃ with small fluctuation

 Equipped with temperature display function, preferably with high temperature alarm

 The door and cabinet body are equipped with good insulation layer, which can quickly return to temperature after opening the door

2. Material and Workmanship

 Liner material: 304 stainless steel is preferred for corrosion resistance and easy cleaning

 Shell material: Spray-coated steel plate or stainless steel for rust and collision resistance

 Door seal: Silicone material with good sealing performance and not easy to deform

 Shelves: Stainless steel shelves with reasonable load-bearing capacity, easy to disassemble and clean

3. Safety and Compliance

 With national mandatory 3C certification

 Structural design avoids sharp corners and meets food safety and hygiene requirements

 Equipped with door lock function to prevent unauthorized access by irrelevant personnel

4. User Experience

 Simple operation with clear temperature setting

 Clean and easy-to-wipe appearance, suitable for placing in prominent positions such as canteens and open kitchens

III. Daily Maintenance

1. Daily/Weekly Tasks

 Check the temperature display every day to confirm it is within 0～4℃

 Simply wipe the door seal and door handle every day to keep them clean

 Thoroughly clean the shelves and liner once a week:

 Wipe with warm water and neutral detergent after power off

 Wipe clean with clear water and air dry naturally

 Check if the door seal is fitted well and whether there is deformation or damage

2. Monthly Tasks

 Clean the condenser (radiator):

 Clean dust with a brush or vacuum cleaner after power off

 Ensure good ventilation and avoid blocking with items

 Check if the power cord and plug are intact and free from aging or damage

 Check if the alarm function is normal

3. Semi-annual/Annual Tasks

 Check if the compressor operates with abnormal noise or vibration

 Ask professional personnel to inspect the refrigeration system and replenish refrigerant when necessary (repair in time if there is leakage)

 Conduct a comprehensive deep cleaning including door seals, gaps and corners

IV. Energy & Cost Saving Guide

The sample cabinet is powered on all year round, so saving energy means saving money.

1. Reasonable Placement

 Keep away from heat sources such as stoves, ovens and steamers

 Place in a well-ventilated location, leaving heat dissipation space at the back and sides (generally ≥10cm)

 Avoid direct sunlight

2. Standard Usage Habits

 Minimize the frequency and time of opening the door, and take and place samples centrally

 Cool hot samples to non-scalding temperature at room temperature before putting them in

 Do not overfill to ensure air circulation, generally leave 1/3 of the space

 Do not open the door for a long time for ventilation to avoid massive cold air loss

3. Scientific Temperature Setting

 It is recommended to set the sample cabinet at 2～4℃, do not set it too low for "more insurance"

 The lower the temperature, the higher the power consumption and the heavier the compressor load

 Regularly check the actual temperature (test with an independent thermometer)

4. Good Maintenance Equals Cost Saving

 Clean the condenser regularly, good heat dissipation can significantly save electricity

 Keep the door seal well-sealed, air leakage will greatly increase power consumption

 Repair problems such as poor door sealing, insufficient refrigeration and loud noise as soon as possible to avoid small problems turning into major faults
