PT. TIARA SERVICE CENTREHisaka Joule Heating Sterilizer (RMS Series) is a revolutionary sterilization system that uses electricity to heat food directly. Unlike conventional methods that heat from the outside in (like a pot on a stove), Joule heating warms the product from the inside out. This allows for ultra-fast processing of liquids containing large solid particles (chunks of meat, vegetables, fruits) without overcooking the surrounding liquid.
Electricity passes through the food itself, generating heat instantly. This eliminates the delay of heat transfer through container walls or slow conduction in thick sauces.
The biggest challenge in food processing is heating solids. With Joule heating, solid chunks heat at the same speed as the liquid surrounding them, ensuring safety without turning vegetables into mush.
Rapid heating and cooling significantly reduces the time product spends at high temperatures. This preserves the natural texture, shape, and nutritional value of the ingredients.
Direct conversion of electricity to heat minimizes energy waste. There are no boilers or steam generators required, reducing utility infrastructure costs.
Space-saving design compared to traditional retort systems. The continuous flow design fits easily into existing production lines.
Stainless steel construction with automated CIP/SIP capabilities ensures high hygiene standards with minimal manual intervention.
The Joule Heating Sterilizer operates by passing electrical current through the food product:
The product (liquid with solids) is pumped through a special heating tube equipped with electrodes.
Electrical current passes through the product. The product's natural resistance to electricity generates heat instantly, warming both liquid and solids simultaneously.
Product reaches target temperature rapidly and is held for the required time to ensure sterility.
Product is quickly cooled using a heat exchanger to preserve texture and quality.
Sterilized product is filled into packages (pouches, trays, or cups) under aseptic conditions.
Hisaka Joule Heating Sterilizer (RMS Series) is the best solution for products with large solid pieces that are difficult to heat conventionally:
Heats the meat center as fast as the curry sauce, ensuring safety without overcooking the vegetables or turning the meat into shreds.
Beef stew, pork stew, and vegetable-heavy dishes where maintaining the shape of chunks is critical for premium quality.
Tomato sauce with chunks, vegetable soups, and side dishes (okazu) requiring gentle heating to prevent mushiness.
Creamy pasta, spaghetti with meat sauce, and noodle dishes where the sauce viscosity and solid ingredients need uniform heating.
Yogurt toppings with fruit chunks, jam with large fruit pieces, and pie fillings.
High-quality purees and meals with soft solid ingredients requiring gentle processing for safety and nutrition.
Conventional heating leaves the center of solid chunks cold. Joule heating ensures the entire product (liquid + solid) reaches sterilization temperature simultaneously.
Short processing time prevents the "mushy" texture often caused by long heating cycles. Vegetables keep their shape; meat stays tender.
Direct heating reduces energy loss. No steam boilers or large heat exchangers are needed, simplifying plant infrastructure.
Unlike batch retorts, this system runs continuously, offering higher throughput and consistent quality for large-scale production.
