Mini Cold Storage for Cloud Kitchens and Delivery-Only Restaurants in Dhaka
Sep
Dhaka’s delivery-only kitchens have changed how food businesses start. Instead of a dining room on a main road, a cloud kitchen rents a modest space — sometimes a converted flat, a ground-floor shop in a back lane or a shared commissary — and sells entirely through delivery apps and social media. Several virtual brands often run from the same kitchen: a biryani brand, a burger brand and a dessert brand sharing staff, equipment and, crucially, refrigeration.
Cold storage is where many of these kitchens struggle. A few domestic fridges and a chest freezer are fine for the first month, then orders grow, menus expand, and the kitchen ends up with food stacked in whatever space is cold. This guide looks at when a cloud kitchen should move to a mini cold room, how its storage needs differ from a normal restaurant, and the practical constraints of installing refrigeration in rented Dhaka premises.
Why Cloud Kitchen Storage Is Different from a Restaurant
A dine-in restaurant has a steady flow of guests through the day. A delivery kitchen has sharp peaks around lunch and dinner, driven by app ordering patterns, with long quiet periods in between. That shapes storage in three ways.
- Heavy batch preparation. To hit delivery times during the rush, kitchens prep marinated meat, gravies, rice components and sauces in advance. That means large volumes of prepared food held chilled for hours, not just raw ingredients.
- Very frequent door openings at peak. During the rush, cooks go in and out of cold storage constantly. Each opening lets warm, humid kitchen air in, which the refrigeration system then has to remove.
- Multiple brands, one cold space. Each brand has its own ingredients, sometimes its own allergen concerns, and staff under time pressure. Without a clear layout, items get mixed, used in the wrong dish or lost at the back until they spoil.
Because of this pattern, the question is not only how much volume you need, but how quickly the system can pull the temperature back after the rush, and how easily staff can find things in seconds.
Reach-In Fridges, Walk-In Chillers and Freezers: Choosing the Mix
| Option | Strengths | Limitations |
|---|---|---|
| Reach-in or under-counter units | Sit at the cooking line; fast access during service | Small capacity; many units add heat and power draw |
| Walk-in chiller (mini cold room) | Holds bulk prep and deliveries; organised shelving | Needs floor space, a suitable wall or roof for the condenser, stable power |
| Walk-in or chest freezer | Frozen stock such as parathas, fries, frozen meat | Different temperature from the chiller, so a separate room or partition is needed |
| Combined chiller and freezer room | One insulated box with two compartments | Design must stop the freezer door opening into a warm corridor |
Most growing cloud kitchens end up with a hybrid: reach-in units at each station for the items needed during service, and a walk-in chiller behind the line for bulk prep and deliveries. A separate freezer section is added when frozen items become a significant share of the menu. Our guide to walk-in cold rooms for restaurants and hotels covers the general principles, and our sizing guide explains how to estimate volume from your stock.
Designing the Cold Room Around Service Rush
A few design choices make a real difference for delivery kitchens:
- Strip curtains or an air curtain at the cold room door reduce warm air entry during rapid in-and-out traffic.
- Self-closing doors with a good gasket stop the door being left ajar when a cook has both hands full.
- Enough refrigeration capacity for pull-down, not just steady holding. A system sized only for a closed room will struggle after every rush. This depends on your menu, door traffic and kitchen heat, so it should be calculated rather than guessed — see our heat load calculation guide.
- Shelving by brand and by stage — for example, one shelving bay per brand, with raw items low and ready-to-use items higher, so drips cannot fall onto cooked food.
- Clear labelling with product, brand, prep date and use-by, so staff follow FIFO or FEFO without thinking.
Placing the cold room close to the prep area rather than at the far end of the premises cuts walking time and, just as importantly, reduces how long the door stays open on each trip.
Food Safety Expectations for Delivery-Only Kitchens
Food businesses in Bangladesh operate under the Safe Food Act, 2013, overseen by the Bangladesh Food Safety Authority (BFSA). Delivery-only kitchens are food businesses like any other, and inspections do happen. BFSA and local authorities have also been increasingly visible in Dhaka on hygiene and food handling. Refrigeration is central to several things inspectors look at:
- Separation of raw meat and fish from cooked and ready-to-eat food.
- Food kept at safe temperatures, with a way to show that it was, such as a daily temperature log or a digital logger.
- Covered, labelled containers rather than open trays.
- Clean shelving, floors and door seals, free from mould and pests.
The exact temperatures you hold should follow your own food safety plan and the guidance that applies to your products; a refrigeration supplier can set the system to whatever set points your plan requires. Our guides to cleaning and sanitising a mini cold room and IoT temperature monitoring cover the record-keeping side.
Installing Refrigeration in Rented Dhaka Premises
Most cloud kitchens are tenants, often in buildings never designed for commercial kitchens. That brings practical constraints that are easy to underestimate:
- Electrical capacity. The building’s sanctioned load from DPDC or DESCO may not cover a cold room on top of cooking equipment and exhaust fans. Check before ordering equipment, not after.
- Voltage fluctuation. Compressors dislike low and unstable voltage. Proper protection is covered in our voltage protection and earthing guide.
- Condenser placement. The outdoor unit needs airflow and must not blow hot air into neighbours’ windows or sit in a closed stairwell. Our condenser placement article explains the options.
- Load shedding. A well-insulated cold room holds temperature longer during outages than a collection of domestic fridges, but you still need a plan — see backup power for mini cold storage.
- Moving out. Modular insulated panels can be dismantled and reinstalled at a new site, which matters for a tenant who may relocate when the lease ends.
A Practical Upgrade Path
Rather than jumping straight to the largest room you can fit, many kitchens grow in stages:
- Stage one: track what is stored where for two weeks — volume of raw deliveries, prepared items, frozen goods — and note which items are being squeezed into unsuitable space.
- Stage two: add a compact walk-in chiller for bulk prep and deliveries, keeping reach-ins on the line.
- Stage three: add or partition a freezer section as frozen items grow, or when you start buying frozen stock in larger lots to secure better prices.
- Stage four: if you open a second kitchen, consider whether one location should act as a central prep hub supplying the other with chilled components.
Common Mistakes Cloud Kitchens Make With Cold Storage
- Relying on domestic fridges built for a family kitchen — they lose temperature quickly with constant door opening and wear out fast in commercial use.
- Mixing brands and stages on the same shelf — leads to cross-contamination and wrong ingredients in dishes.
- Overfilling the room so air cannot circulate — creates warm spots even though the display shows the right temperature. See our guide to airflow and stacking clearance.
- Ignoring the condenser location — a unit trapped in a hot, closed space runs constantly and fails early.
- No temperature records — leaves the business unable to show an inspector, or an aggregator’s quality team, that food was stored safely.
