Food Industry

The food industry is a sector where Gas has numerous applications. Cooking and baking are the primary uses of
Gas in the food industry where it provides very good temperature control. Drying applications are also popular in
food processing especially of fish and sea food. It is used also for steam, hot water production and sterilisation
processes, especially in processing of canned meat. Gas is used for all possible food-finishing applications from
boiling, frying, stewing, simmering and baking to grilling, roasting, braising and milk drying.
In baking applications, Gas is a preferred fuel for crispy biscuits, chips, bread, fluffy pastries, spongy cakes and
all types of high quality bakery and confectionary products.
Gas can be used for direct firing which realises major cost savings (reducing investment costs and maximising
thermal efficiency). It is used in drying, boiling as well as sterilisation processes.
Another sub-sector of the food industry where Gas provides solutions is in the manufacture of beverages. Gas
powers the production of CO 2  used to carbonate soft drinks. It is also consumed in the dehydration of food
products such as milk, coffee and chocolate to form instant powders.
It is also widely used by hotels, restaurants, bakeries, canteens and businesses at the front end of the food
industry where a responsive, reliable energy supply is an essential ingredient.
Precision temperature controls, easily handling in small burners and low sulphur content makes final products
palatable and ensures that they pass all statutory tests for human consumption.
Steam from Gas combustion is widely used in the food industry as a heating medium (processing of pasta and
yoghurt) and in some cases a moisturising agent.
These characteristics make Gas the preferred fuel in the food industry.


Baking is a cooking method by dry heat without direct exposure to a flame, typically in an oven. Though bread is
one of the commonest baked products, other products such as cake, bread, potatoes, and biscuits are also
baked using Gas ovens. In addition to these, Gas ovens can be used for water drying or paint baking or powder
curing. Gas ovens provide heat that is gradually transferred from the surface of cakes, cookies, and breads to the
centre and as heat travels through, it transforms batters and doughs into baked goods with a firm dry crust and a
softer centre.
Restaurants, food outlets, hotels and residential, flight kitchens, bakeries, fast food training institutes, pizza
vending stations, educational institutions etc are increasingly using Gas to bake their products for the customers
and for domestic purposes.  Meat, including cured meats, such as ham, biscuits, potatoes, pizza etc can also be
baked using Gas. Today, manufacturers are also producing more Gas-powered ovens to keep pace with the
demand for ovens that are cost effective and environmentally friendly.


  1. Available Space for Tank installation
  2. Easy and user-friendly controls
  3. Cost-effective operations
  4. Maximum reliability and safety assured


  • It makes use of clean energy that is environmentally friendly.
  • Gas is cheap, available and easily transportable fuel source for bakers and baking different products
  • Gas fast heating speed ensures improved bread quality and good heat preservation.

Steam Generation

Saturated Steam is generated by steam boilers/generators either as main generation plants, or at various
process units requiring heat from various sources. Despite modern technology, gas boilers are still the most
common appliances to provide the heat energy to generate steam. Gaseous fuels are without any question the
easiest fuel to combust with the least danger of fouling a boiler.
There are different types of boilers depending on size and energy source requirements.
Heaters (commonly fire-tube and water-tube boilers) may utilise any one or a combination of fossil fuels including
refinery gas, natural gas, fuel oil, and powdered coal.
Gas has emerged as a fuel source of choice due to its environmentally friendly nature. Apart from costs,
sustainability and fuel emissions have now become very important major fuel selection criteria for industrial
Gas is cleaner when compared to other fossil fuel options as it can be considered as sulphur-free and allows for
the easy reduction of NO x , which minimizes acid rain, carbon emissions as well as eliminates soot
emissions. Solid fuels and fuel oils require supplemental anti-pollution devices to clean combustion products to
meet environmental standards. This further lends to the argument that Gas is the clean and cost-effective option.

Water Heating

For the continuous production of hot water in commercial and industrial applications, gas fired water heaters are
the perfect answer. They achieve efficiency and economy of operation by separating the hot water generation
from the space heating requirements.
The heaters can be sized to accommodate specific applications and in many instances, located close to the point
of use thus eliminating transmission losses and reducing installation and running costs.
For applications where there is a constant demand for hot water or where demand peaks at specific times (ie
sports facilities and hotels) fast recovery rates ensure there is plenty of hot water when it is needed. Of particular
significance to the healthcare and education sectors, gas fired water heaters eliminate the conditions that allow
legionellae to be present.
System options include continuous flow, high efficiency Gas hot water systems as well as Gas Boosted Solar
units, condensing boilers and conventional water storage heaters. Hybrid water heaters combining Gas Heat
Pump technologies can provide very high efficiencies and reduce running costs.


  • Gas systems function even at freezing temperatures.
  • Gas hot water systems are quiet.
  • The use of Gas eliminates worries about peak and off peak electricity rates.
  • Usually space efficient with little visual pollution for better aesthetics.
