When it comes to large-scale food production — whether you are manufacturing fruit jams, curry pastes, chocolate fillings, or ready-to-eat sauces — temperature control is everything. Burn your product, and you lose an entire batch. Heat it unevenly, and you compromise quality and shelf life.This is where steam jacketed kettles come in.
Unlike direct-fired cooking vessels, a steam jacketed kettle uses indirect heating, circulating steam through a hollow jacket surrounding the inner cooking chamber. The result? Gentle, uniform, and highly controllable heat — no scorching, no hot spots.
At Shandong Longze Machinery Co., Ltd., we have spent 14 years engineering steam cooking kettles that food processors around the world trust. From compact 100-liter units for artisanal kitchens to massive 1000-liter systems for industrial production lines, our kettles are built to handle the most demanding recipes. Applications: What Can You Cook in a Steam Jacketed Kettle?
Our steam kettles are purpose-built for viscous, heat-sensitive, and particulate-rich food products: 1. Fruit Jams & Preserves
The gentle steam heating prevents sugar from caramelizing too quickly, giving you better control and retaining natural fruit color and flavor. Ideal for strawberry jam, blueberry preserves, marmalade, and fruit compotes. 2. Curry Pastes & Sauces
Thai green curry, Indian tikka masala base, Japanese curry roux — all require long, slow simmering without burning at the bottom. The scraper agitator ensures continuous mixing while the indirect steam maintains a steady temperature. 3. Pie Fillings & Bakery Fillings
Apple pie filling, custard, chocolate ganache, cream fillings — all demand precise temperature control to avoid scorching dairy or breaking emulsions. Steam jackets deliver that precision. 4. Tomato-Based Sauces
Pasta sauces, pizza sauce, ketchup — high-acid products that can react with direct heating elements benefit from the neutral stainless steel contact surface and indirect heating of a steam kettle. 5. Ready-to-Eat Meals & Soups
From lentil soups to beef stews, large-volume batch cooking requires uniform heat distribution across 500L or more. Our 1000L kettles are designed for exactly this scale. 6. Confectionery & Syrups
Caramel, toffee, sugar syrups, and glucose mixtures all benefit from the controlled heat ramp-up and consistent temperature maintenance of steam heating.
For facilities that already operate a steam boiler — common in medium to large food processing plants — steam jacketed kettles are the most energy-efficient and product-safe option. Contact me for more information:
