Deep freezers for restaurants, cloud kitchens and caterers
By Sadguru Research & Analysis Laboratory · 23 October 2026
Frozen storage is where many small food businesses quietly lose quality and money: freezer burn, thawing during power cuts, and mixed raw and cooked stock. A good double-door deep freezer, run properly, solves most of it.

Temperatures that matter
Frozen food should be held at −18 °C or colder. Convertible freezers can also run as chillers (0–5 °C) for dairy and marinated items. Keep a probe thermometer and log the temperature twice a day, which FSSAI inspectors like to see.

Power cuts
A full, closed chest freezer holds temperature for many hours. Do not open it during a cut. If food has thawed above 5 °C for more than a couple of hours, do not refreeze it.
Common questions
Chest freezer or upright freezer for a restaurant?
Chest freezers hold temperature better when opened and use less power; uprights are easier to organise. Most small kitchens choose double-door chest models.
Can frozen food go bad?
Freezing stops bacterial growth but does not kill bacteria. Quality drops over time, and food can spoil quickly once thawed.
Test before you spend
A laboratory report tells you exactly what your water or food needs, so you buy the right equipment once. We test water to IS 10500 and food to FSSAI standards, with sample pickup across Kolkata.
