CASTA Electric Dim Sum Steamer 24 Litre with Bamboo Containers

A dim sum steamer generates moist heat by boiling water in a sealed tank, then directing the steam upwards through perforated trays. The steam surrounds the food evenly, cooking it gently without drying or scorching. Because the heat is transferred by vapour rather than by air or oil, the process preserves colour, texture and nutrients better than frying or baking. The closed system also keeps flavours distinct, so each basket can hold a different dish without cross-contamination.

The operator fills the tank with water to the marked level, either automatically or by hand. Once the power is switched on, the sheathed elements heat the water until steam rises. Bamboo baskets are stacked on the perforated plate, and the lid is closed to trap the steam. A safety interlock prevents the elements from operating if the water level falls too low, and an overflow pipe prevents spillage. After the set time, the baskets are lifted out and replaced with the next batch.

The unit is built entirely of AISI 304 stainless steel with a Scotch Brite finish. The work surface is 1.2 mm thick, rounded at the edges for hygiene and comfort. The steaming tank is pressed with rounded corners and includes an overflow pipe. High-efficiency sheathed heating elements sit inside the tank and are protected by a safety device that cuts power if the water level drops below the minimum. An automatic refill system keeps the tank topped up; manual refill is also possible if the automatic system fails.

A perforated stainless-steel plate supports the bamboo baskets, and a sealing gasket around the lid retains steam for even cooking. The stand is open, allowing the unit to be positioned over a worktop or shelf. Control knobs are made of heat-resistant material with cool-touch technology.

The 24 L capacity corresponds to a gastronorm 1/1 tray, allowing standardised portioning and storage. The 3.5 kW power rating requires a 400 V three-phase circuit, which is typical for heavy-duty catering equipment. The 400 mm depth, 700 mm width and 850 mm height determine the space it occupies on the floor or worktop. The bamboo containers are included and are sized to fit the perforated plate.

Cleaning involves draining the tank, wiping the stainless-steel surfaces with a damp cloth and mild detergent, and rinsing the bamboo baskets. The rounded corners and Scotch Brite finish reduce the risk of trapped food particles. The overflow pipe and automatic refill system minimise scale build-up, but periodic descaling of the tank is recommended to maintain steam efficiency.

The model is supplied with bamboo containers as standard. It is designed for professional kitchens that prepare dim sum, dumplings and other steamed dishes.
