The Core Difference between The Jacketed And Non-jacketed Stainless Steel Agitator Tanks

The core difference between the jacketed and non-jacketed stainless steel agitator tanks lies in whether they have temperature control functions. This leads to multi-dimensional differences in structural design, applicable scenarios, cost and maintenance, etc. The specific comparison is as follows:

I. Core Function: Temperature control capability is the key dividing line. 1. Jacketed agitator tank: Equipped with a "Temperature regulation layer" - Core Function: By introducing heating or cooling media (such as hot water, steam, cold water, heat transfer oil) through the jacket (the annular interlayer on the outside of the tank), precise temperature control (heating, holding, and cooling) of the materials inside the tank is achieved. - Temperature control accuracy: When used in conjunction with a temperature control system (such as a PID controller), the temperature control accuracy can reach ±1℃, which can meet the temperature-sensitive process requirements of materials (such as heating dissolution, constant temperature reaction, and cooling crystallization). 2. Non-jacketed agitator tank: It only has the basic function of "mixing and stirring" - Core function: It has only a single-layer stainless steel tank body and can only achieve the mixing, dispersion and stirring of materials through the stirring paddle. It has no active temperature control ability at all. The temperature inside the tank is completely dependent on the ambient temperature or the material's own reaction (if there is an exothermic/endothermic reaction, the temperature will fluctuate naturally). - Temperature limitation: It cannot actively adjust the temperature. If the material requires a specific temperature environment (such as constant temperature mixing at 30℃), additional external equipment (such as water bath POTS, hot air furnaces) must be used. The temperature control efficiency is low and uneven.

Ii. Structural Design Is there an additional layer of "jacket structure"? Comparison dimensions: Jacketed agitator tank; Non-jacketed agitator tank | -- -- -- -- -- -- -- -- - - - - - - - - | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | | tank structure | Double-layer structure (inner material tank + outer jacket), with reserved medium inlet and outlet and sewage outlet in the jacket; single-layer structure (only material tank), no additional interlayer; auxiliary components: medium transfer pump, temperature control valve, insulation layer required (optional to reduce heat loss); no additional components It only contains the stirring motor, blades, and feed/discharge ports. Sealing requirements: The connection between the jacket and the tank body needs to be double-sealed (to prevent medium leakage), and the sealing cost is high. Only the sealing of the material tank needs to be ensured (to prevent material leakage), and the structure is simple. Weight and volume: Due to multiple jackets and insulation layers, Under the same capacity, it is 30%-50% heavier than the non-jacketed model and occupies a slightly larger area. It is light in weight and compact in volume, saving more space under the same capacity

Iii. Applicable Scenarios: Matched according to "Material Process Requirements". 1. Jacket type: Suitable for "temperature-sensitive" processes - Typical industries/materials: - Food and Chemical Industry: Sauce heating and boiling, constant temperature reaction of medicinal liquid, chocolate melting and heat preservation; - Biomedicine: Enzymatic hydrolysis reaction (requires constant temperature at 37℃), vaccine refrigeration and stirring (requires cooling at 2-8℃); - Coatings and inks: The resin is heated to dissolve, and the pigment is dispersed and then cooled to set. - Core requirement: As long as the material process involves "heating/cooling/constant temperature", the jacketed type must be selected. 2. Non-jacketed type: Suitable for "normal temperature mixing type" process - Typical industries/materials: - Building materials: dry-mixed mortar mixing, concrete additive stirring (normal temperature does not affect performance); - Daily chemical and light industry: Mixing of laundry powder particles, stirring of ordinary dishwashing liquid (no temperature control required); - Storage and batching: Temporary storage and stirring of solid particles/powders (only to prevent caking). - Core requirement: Material mixing does not require temperature intervention, or the ambient temperature can meet the process requirements. The non-jacketed type can be selected.

Iv. Cost and Maintenance Jacketed type "high initial investment + more later maintenance"! Comparison dimensions: Jacketed type agitator tank: Non-jacketed type agitator tank | -- -- -- -- -- -- -- -- - - - - - - - - | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | | purchasing cost | High (40%-80% higher than the non-jacketed model of the same capacity), due to multi-jacket processing and temperature control components; low (simple structure, no additional temperature control parts); high operating cost (requires consumption of heating/cooling media, such as steam and electricity; The insulation layer needs to be inspected regularly. Low (only consumes electricity for the stirring motor, no other energy consumption). High maintenance difficulty (needs to be checked regularly for leakage of the jacket, blockage of the medium channel, and aging of the sealing parts). Low (only requires maintenance of the stirring motor and cleaning of the tank, with few faults). Impact on service life: If the jacket is corroded and leaks, It may affect the overall lifespan of the tank and requires professional maintenance. The structure is simple and there are no vulnerable jacket parts, so its lifespan is relatively longer
