Cake showcases are the "sweet housekeepers" of bakeries and families. Scientific maintenance can improve refrigeration efficiency and extend service life. The following are practical tips:
1. Daily cleaning
Wipe the inner wall with a soft cloth dipped in neutral detergent every week to avoid scratching the evaporator with a hard brush. Be sure to wipe off water stains after cleaning to prevent frost or bacteria.
2. Stable temperature control
Set the appropriate temperature (usually 0-4℃ for refrigeration and -18℃ for freezing), and avoid frequent opening and closing of the door. The loss of cold air when the door is opened will increase the burden on the compressor.
3. Reasonable placement
Keep away from heat sources (such as ovens, heaters) and avoid direct sunlight. Ensure ventilation around the showcase, and reserve ≥10cm of heat dissipation space at the bottom.
4. Regular defrosting
If the frosting thickness exceeds 5mm, it is necessary to turn off the power for defrosting. After natural melting, wipe off the accumulated water to prevent water from flowing into the circuit. New air-cooled showcases do not require manual defrosting.
5. Check the seal and drain hole
Check the door seal for deformation every month. You can use banknotes to test the seal (it is better if the banknotes are not easy to pull out after closing the door). Clear the bottom drain hole to prevent water accumulation and odor.
Tips: Deep cleaning once a year, including dust removal of the condenser filter, can save more than 10% of energy.
Scientific maintenance makes the cake showcase run efficiently and protects every bite of freshness!
