Multi-purpose liquid tank: which solutions does it hold on a dried fruit line?

A dried fruit line works with several liquids: wash water, brine and cleaning solutions among them. The multi-purpose liquid tank is described in our catalogue as a storage tank that holds liquid products such as oil, water and acid. This article explains which liquids it suits and what is checked before one is specified.

It is a holding vessel. Following the catalogue record, different liquids such as oil, water and acid can be stored in the same tank, and the structure is built to be easy to clean. The machine does not mix or treat a solution inside the process. Its job is to keep a ready liquid safely and release it to the line when it is needed.

This is different from the salt dissolving tank, which prepares brine by dissolving salt in water. The multi-purpose tank is the flexible vessel that stores the prepared solution.

The catalogue names three examples: oil, water and acid. Any other liquid needs a compatibility check, because whether a liquid suits a tank depends on the material and the operating conditions. Typical uses beside a processing line are:

• 01Process water: wash water held next to the line before or after use.
• 02Brine: storage of a salt solution prepared in another tank. Preparation itself is done in the salt dissolving tank.
• 03Oil: liquid oils used within the line.
• 04Acid solutions: acidic liquids used for cleaning or process purposes. Material grade matters most here.
• 05Cleaning liquids: solutions kept ready between shifts or at the end of the line.

The concentration and temperature of each liquid depend on the plant's own process. The catalogue does not give fixed figures for them.

The catalogue lists the body as AISI 304 stainless steel. The product contact surface is also AISI 304, with AISI 316 optional depending on the process. Not every configuration comes in 316; it is an option used when the liquid calls for it.

General materials references note that chloride-rich liquids such as brine raise the risk of pitting and crevice corrosion in stainless steel, and that molybdenum-bearing 316 resists these better. For acids, the choice depends on the type of acid and its concentration. This is general knowledge, not a promise about the life of a specific tank. The final decision is made at quotation stage once the liquid and its conditions are known.

The catalogue says different liquids can be stored in the same tank. In practice that means one tank can serve different liquids in turn. Two points matter then: the tank must be drained and cleaned fully between liquids, and residue from one must not affect the next. This is why easy-to-clean construction is listed as standard equipment. It is also good practice to record which liquid each tank has held.

The plant only needs to share a few items: the name of the liquid, its temperature, the daily fill and drain routine and the available floor dimensions. Without them no capacity or material figure is given; values vary by project and exact values are confirmed in the quotation.

To see the other products in the group, open the tanks category. For an example of a line that uses salt water, see the dried fig washing line.

Send the liquids you plan to store, their temperature range and your layout dimensions, and we confirm together whether AISI 304 or AISI 316 is needed for the contact surface. You can request a quote or first read the technical record on the multi-purpose liquid tank page.
