The cake cabinet refrigerated display cabinet is a key piece of equipment for bakeries, dessert shops, and other places to store cakes and desserts. Whether the temperature adjustment is appropriate directly affects the freshness, taste, and storage time of the food. Proper temperature adjustment can not only ensure the quality of the food but also save energy consumption. The following is a detailed introduction to the temperature adjustment method and related precautions of the cake cabinet refrigerated display cabinet.

Define the appropriate temperature range：

Before adjusting the temperature, it is first necessary to be clear about the appropriate refrigeration temperature for cakes and other desserts. Generally speaking, the best refrigeration temperature for cake - type foods is between 2 - 8℃. This temperature range can effectively inhibit the growth of bacteria, slow down the spoilage rate of cakes, and at the same time, maintain the taste and flavor of the cakes to the greatest extent. If the temperature is too high, bacteria are likely to multiply and the cake is prone to spoilage; if the temperature is too low, the cream in the cake may solidify and the taste may become hard, affecting the eating experience.

Temperature adjustment methods for different types of display cabinets

(1) Mechanical knob - type adjustment

Find the temperature adjustment knob: Usually, for mechanical knob - type cake cabinet refrigerated display cabinets, the temperature adjustment knob is located on the side or back of the display cabinet. The knob is generally marked with numbers from 0 - 7, and some display cabinets also mark the corresponding temperature range.

Understand the meaning of the knob scale: The number 0 usually represents the shutdown state. The larger the number, the lower the refrigeration temperature. Generally, the temperature corresponding to number 1 is about 8 - 10℃, the temperature corresponding to number 2 is about 6 - 8℃, the temperature corresponding to number 3 is about 4 - 6℃, the temperature corresponding to number 4 is about 2 - 4℃, and the temperature corresponding to number 5 and above is lower than 2℃.

Carry out temperature adjustment: According to actual needs, rotate the knob to the appropriate scale. For example, in spring and autumn, when the ambient temperature is more suitable, the knob can be adjusted to gears 3 - 4, keeping the temperature at 4 - 6℃; in summer, when the ambient temperature is high, in order to ensure the refrigeration effect, the knob can be adjusted to gears 4 - 5, keeping the temperature at 2 - 4℃; in winter, when the ambient temperature is low, the knob can be adjusted to gears 2 - 3, keeping the temperature at 6 - 8℃.

(2) Electronic button - type adjustment

Get familiar with the control panel: For electronic button - type display cabinets, the control panel is usually on the front of the display cabinet, with a temperature display screen and various function buttons, such as "temperature adjustment", "setting", "confirmation", etc.

Enter the temperature adjustment mode: Press the "temperature adjustment" or "setting" button. At this time, the numbers on the temperature display screen will flash, indicating that the temperature adjustment mode has been entered.

Set the target temperature: Adjust the temperature value by pressing the "+" and "-" buttons, and set the temperature to a suitable value between 2 - 8℃. Each time the button is pressed, the temperature will increase or decrease by 1℃ accordingly.

Confirm the temperature setting: After setting the target temperature, press the "confirmation" button. The numbers on the temperature display screen will stop flashing, indicating that the temperature setting is successful, and the display cabinet will operate according to the set temperature.

Precautions for temperature adjustment：

Avoid frequent adjustment: After the temperature is adjusted, the display cabinet needs a certain amount of time to reach the set temperature. Frequent temperature adjustment not only increases energy consumption but also affects the service life of the display cabinet. It is recommended to observe for 2 - 4 hours after adjusting the temperature. After the temperature is stable, decide whether to adjust it again according to the actual situation.

Consider environmental factors: The ambient temperature, ventilation conditions, etc. of the display cabinet will affect its refrigeration effect. If the display cabinet is placed in a place with direct sunlight, poor ventilation, or near a heat source, its refrigeration efficiency will be reduced. At this time, it may be necessary to adjust the temperature lower.

Calibrate the temperature regularly: Due to long - term use or other factors, the temperature of the display cabinet may deviate. It is recommended to regularly measure the actual temperature inside the display cabinet with a thermometer. If a large deviation from the set temperature is found, calibration should be carried out in a timely manner.

Pay attention to the amount of food stored: Too much or too little food stored in the display cabinet will affect the stability of the temperature. When storing food, avoid overcrowding to ensure that the cold air can circulate normally; at the same time, do not store too little to prevent the cold air from flowing away too quickly.

Common problems and solutions

No refrigeration after temperature adjustment: First, check whether the display cabinet is connected to the power supply and whether the power socket is normal. If the power supply is normal, it may be due to improper temperature adjustment, such as turning the knob to gear 0 or setting a too high temperature electronically. At this time, the temperature should be adjusted again. If there is still no refrigeration, it may be a malfunction of components such as the compressor, and professional maintenance personnel should be contacted for repair.

Food freezes due to too low a temperature: In this case, it may be that the temperature is set too low. The temperature should be adjusted appropriately. If the problem is still not solved, it may be a malfunction of the temperature sensor, and professional maintenance is required.

Properly adjusting the temperature of the cake cabinet refrigerated display cabinet is an important part of ensuring the quality of cakes and other desserts. It is hoped that through the above introduction, everyone can master the methods and techniques of temperature adjustment, so that the display cabinet can better serve the business.
