PRODUCT DESCRIPTION
Storage mixing tanks are engineered vessels designed for the safe containment and management of liquids,
semi-liquids, or gases across sanitary and industrial environments.
They are commonly manufactured from Stainless steel to ensure hygiene,
corrosion resistance, and long-term durability.
These tanks are widely used in food and beverage processing, pharmaceuticals,
chemicals, cosmetics, and water treatment systems.
Their designs can include vertical or horizontal configurations,
insulated or non-insulated structures, and optional features such as agitators,
level indicators, and manways. By providing controlled, hygienic storage,
storage tanks help maintain product stability, prevent contamination, and support efficient production workflows.
Have different kinds of agitators:
1, Bottom magnetic agitator with propeller impeller, speed from 50-400rpm or 50-800rpm. this kind of agitator is mixing thin viscosity , such as eyedrop, injection, CIP liquid, water, etc.
2, Top mechancial agitator with propeller impeller, speed at fix 71rpm or adjustable 20-200rpm or special requirement. this kind of agitator is mixing syrup, injection, blood, oral liquid, culture media, etc.
3, Top mechanical agitator with anchor or frame impeller, speed is from 10-70rpm. it is mixing higher viscosity , such as sediment or viscosity oral liquid, etc.
4, Top emusification homogenizer, speed max 2900rpm for small vessel, 1480rpm for bigger tank. this kind of agitator is mixing most high viscosity , such as suspension, oil, fat emulsification , etc.
5, Bottom emusification homogenizer, speed max 2900rpm for small vessel, 1480rpm for bigger tank. this kind of agitator is mixing most high viscosity , such as suspension, oil, fat emulsification , etc.

Working Principle
The working principle of storage tanks focuses on secure containment combined
with controlled handling of stored media. Fluids enter the tank through inlet connections and
are held under stable pressure and temperature conditions suited to the process requirements.
Depending on application needs, tanks may integrate mixing, heating, cooling,
or circulation systems to maintain uniform composition.
Outlets allow controlled discharge for downstream processing,
while venting and sealing components ensure safety and cleanliness.
Through precise structural design and process control, storage tanks enable reliable material management,
reduced losses, and consistent product quality throughout industrial and sanitary operations.

Production Buffer Blending Preparation Tank – Comprehensive Guide
The Production Buffer Blending Preparation Tank is a critical component in modern industrial processing. Engineered for precise liquid handling, mixing, and storage, these tanks are widely used in pharmaceutical, food, chemical, and cosmetic industries. Optimized for sanitary operations, they ensure high efficiency, product consistency, and regulatory compliance.
In today’s competitive manufacturing environment, the ability to maintain uniform product quality while reducing processing time is paramount. Production buffer blending tanks meet these needs by combining robust construction, intelligent design, and versatile functionality, supporting large-scale batch operations without compromising hygiene or performance.
A Production Buffer Blending Preparation Tank is a vessel designed for preparing, mixing, and temporarily storing liquid formulations before they move to downstream processing. The term “buffer” refers to its role in stabilizing production flow, ensuring continuous operations without interruptions.
Primary purposes include:
·
Homogenizing raw materials or intermediate solutions
·
·
Maintaining consistent temperature and viscosity
·
·
