Food grade tanks are constructed in compliance with Food and Drug Administration regulations regarding the handling and processing of food for general consumption. Many are made with FDA approved coated carbon steel and stainless steel that is thermally cured. Additionally, high density polyethylene or polyurethane are used to manufacture food grade storage tanks due to their resistance to solvents and chemicals. Read More…
Food Grade TanksFood grade tanks are sanitary metal containers used for food processing and storage. Because of FDA regulations and standards for food handling and processing in terms of sanitation and bacteria growth, 304 stainless steel is a suitable material to use when handling, preparing and storing consumable substances like fruit, meat, milk or vegetables.

The food processing industries, such as brewing, meat packing, and bakeries,
depend on well designed and constructed food storage tanks to safely and
hygienically store their ingredients. Stainless steel tanks are used to mix
meat with additives or blend sausage. The brewing industry depends on food
grade tanks for use as fermentation vats for adding yeast, while 304 stainless
steel tanks are used in the citrus and fruit juice industry from harvest to
Water food grade tanks hold water for industrial, residential, and
agricultural use and range in sizes from a few gallons up to tens of thousands
of gallons. Water food grade tanks are made of a variety of materials
including stainless steel, steel, and high grade plastics.
Types of Food Grade Tanks
Horizontal tanks may be located above or below ground. Their length is no
greater than six times their diameter to ensure structural integrity.
Horizontal tanks have pressure vacuum vents, gauge hatches, and sampling
wells. They are an alternative for food storage when inside space has limited
Metal underground tanks are cathodically protected to prevent tank casing
corrosion. They have galvanic anodes inside the tank or sacrificial anodes
connected to an impressed current system that are used for cathodic
Multi-compartment food grade tanks are designed to hold multiple food products
with different temperature requirements and can have up to four individual
compartments. The individual compartments are insulated to allow for the
variations in temperature between the compartments, which are pitched for easy
Cone Bottom Tanks
Cone bottom tanks are funnel shaped with a drain at the center bottom of the
tank. They are ideal for the storage of solid food materials and allow for
easy access. The bottom of a cone bottom tank is referred to as its head and
can be used for mixing or storing of food products. The design of cone bottom
tanks ensures that all ingredients are drained from the tank since it has a
12o pitch to it. Cone bottom tanks work well with mixers and are customizable
to fit the needs of a process.
Cook and Chill Tanks
Cook and chill tanks are designed to cook meat, poultry, vegetables, and pasta
to a "just-done” limit after which the food is chilled for storage such that
it can be reheated. The cooking process for a cook and chill tank is completed
using steam from a boiler, a heat transfer process, direct fire, or electric
heating. Most cook and chill tanks are made of stainless steel and are
The process for cook and chill tanks is also used to complete hands-free
mixing of ingredients. Operators program the temperature and the speed of the
agitator. The cook and chill tank completes the process without any further
interference. A major benefit of cook and chill tanks is the reduction of
manpower required to complete cooking processes. Cook and chill tanks are used
by large food service organizations such as hospitals and universities.
Slope Bottom Tanks
Slope bottom tanks have a flat bottom that slopes at an angle on one side,
which guides product to the side outlet for access and release. They are used
with low viscosity fluids like milk, broths, and lighter granular products.
Food Grade Silos
Food grade silos are vertical storage units that can hold between one thousand
and ten thousand gallons. They are an efficient space saving method for
storing products and keeping them protected. In most cases, food grade silos
are custom made from steel and stainless steel to meet the specific needs of
customers. Smaller food grade silos are made from plastic and come with
sloped, flat, dish, and cone shaped bottoms.
Food Grade Tank Bottoms
The bottom of a food grade tank, referred to as the head, is an essential part
of a tank since its design will enhance the use of a tank and increase its
efficiency. In most cases, the bottom of a food grade tank isn’t something
that most clients consider when purchasing a food grade tank. It becomes a
factor when dispensing product from a tank and can cause complications.
The four basic bottoms to food grade tanks are flat, sloped, cone shaped, and
dish. The various types of bottoms have to align with the process that they
are connected with, which can be mixing, storing, draining, or recirculating
and may include proprietary processes.
Cone bottoms are funnel shaped and have a drain at the center and bottom of
the funnel. The cone shaped bottom is the most common one used in food
processing since it makes it easier to drain products with a high solid
content. Cone bottoms are ideal for the limitation of fluid flow.
Dish bottom tanks have a similar construction as that of cone bottom tanks
except that the bottom has the shape of a dome with a drain at the lowest part
of the curve of the dome. The shape of a dish bottom helps in fluid
circulation and is a better geometry for solid suspensions and slurries. The
dome shape of dish bottom tanks makes them more rigid due to the strength of
the curve of the dome and its knuckle radius.
The major benefit of slope bottoms is the ease of access to the drain that
sticks out away from the bottom of the tank. The angle of the slope of a slope
bottom tank can be adjusted to better fit the application for which it is
Flat bottoms are the most flexible of the bottom configurations since they can
adapt to a variety of processes and have moderate fluid and solid flow. Of the
four forms of bottoms, flat bottoms are the least expensive because of their
simple design and ease of manufacturing. Flat bottom food grade tanks require
a shorter mixing shaft than that designed for cone and dish shaped bottoms.
The drawback of flat bottoms is that the tanks do not drain well, which limits
the products that can be mixed or stored in them.
Choosing the Right Food Grade Tank Manufacturer
To make sure you have the most positive outcome when purchasing food grade
tanks from a food grade tank manufacturer, it is important to compare at least
5 manufacturers using our food grade tank directory. Each food grade tank
manufacturer has a business profile page that highlights their areas of
experience and capabilities and a contact form to directly communicate with
the manufacturer for more information or request a quote. Review each food
grade tank business website using our proprietary website previewer to get an
idea of what each company specializes in, and then use our simple RFQ form to
contact multiple food grade tank businesses with the same form.
