Feeding the world is a big job. Food processing is an industry wherein gas is used right from the start of the producing process until the end.

Farming

Environmental changes disrupt the natural process of drying the crop. Since global warming has affected the Earth’s climate, identifying methods to dry crops is becoming a challenge for framer globally. This is where LPG helps. It is the most economic fuel which can be used to dry crops such as wheat, potatoes, barley, maize, onions, corn, fruits, grain, rice, cereal, tobacco etc.
LPG is used to power dryers more efficiently and effectively, preserving the economic value of the crop regardless of the weather. They also limit fungus and bacterial growth, allowing farmers to harvest their crops with flexibility.

Other advantages:

  1. LPG is nontoxic and safe around food materials.
  2. Emissions from propane burners are lower.
  3. LPG can be stored for extended periods of time, while gasoline or diesel fuel tends to turn rancid.
  4. Gasoline or diesel fuel spills contaminate water, land, and crops, any propane leak vaporizes instantly.

Dairy

Milk is a highly perishable commodity. Its nutrients make it a favourable medium for the growth of microorganisms. Therefore, it is essential that milk is subjected to certain treatments. Electric water heating turns out to be an expensive affair. LPG gives a cost advantage and is a reliable source for generating hot water supply. The hot water is used for cleaning of milk lines, storage tanks, controlling total bacteria count, processing milk and milk products, pasteurisation, sterilization, temperature control of dairy shed and so on. The steam generated from the hot water is used for sterilization of milk and dairy equipment.

Verka is a brand of Milkfed in Punjab, India. It is well known for milk production and manufacturing of fresh milk products.

Bakery

Cakes, breads, potatoes, biscuits, cookies, pizzas, brownies, muffins etc. are all a part of our diet. They are all baked using LPG fired ovens directly or indirectly via heat exchangers. In direct baking gas ovens, heat that is gradually transferred from the surface of cakes, cookies, and breads to the centre. As heating carries on, it transforms batters and doughs into baked goods with a firm dry crust and a softer centre. In indirect heating, the baking chamber is indirectly heated from above and below by the thermal radiation generated by high-temperature rows of steel tubes/ducts (exchangers). The tubes/ducts, which run the length of the oven, are first heated by hot air and combustion gases flowing inside of them.
Britannia Industries is one of India’s leading food companies with a 100-year legacy. It is among the most trusted food brands, and manufactures India’s favourite brands like Good Day, Tiger, NutriChoice, Milk Bikis and Marie Gold which are household names in India. Britannia’s product portfolio includes biscuits, bread, cakes and rusk.

Poultry Farming

In poultry farming, aspects like temperature, humidity and air renewal are essential. LPG helps provide the environmental factors in a cleaner and efficient manner. LPG radiant heaters ensure that sheds and brooder houses heated to the optimum temperature which in turn influences feeding, sleeping, weight gain and feathering. It powers hot water pressure washers which are used to sanitize pens, machinery and other farm equipment. This promotes health of the poultry and prevents the spread of diseases. LPG is also used for bath heating (cleaning the poultry), steam generation(sterilization) and drying (the poultry before sale).

Beverages

Whether it is coffee, tea, wine, whiskey, brandy, beer or any of your favourites, gas is used right from its production to its consumption.

Tea:

Tea gardens require a clean and fresh atmosphere for cultivation. Gas being a clean source of energy is the most preferred choice. Gas is being used for processes like:

  1. Wilting: Withering is used to remove excess water from the leaves and allows a very slight amount of oxidation.
  2. Oxidation: For teas that require oxidation, the leaves are left on their own in a climate-controlled room where they turn progressively darker.
  3. Kill-Green: This process is accomplished by moderately heating tea leaves, thus deactivating their oxidative enzymes and removing unwanted scents in the leaves, without damaging the flavour of the tea
  4. Sweltering: Unique to yellow teas, warm and damp tea leaves from after kill-green are allowed to be lightly heated, which causes the previously green leaves to turn yellow.
  5. Drying: It is done to “finish” the tea for sale.

Coffee:

Coffee is a major international commodity. Drying and roasting of the beans are most important operations as they affect a bean’s aroma, flavour and acidity. Use of gas makes it possible to provide both control and uniformity throughout the drying process thus, giving superior quality beans as the output. It allows flame modulation which results in better efficiency and savings.
The most common roasting machines are:

  1. Drum: LPG heats the drum. Green beans inside the drum get roasted due to the heat. Specially designed stirring vanes inside the drum provide the beans with homogenous heat transfer. Roasting cycle inside the drum is checked by sampling spoon, sight glass and heat control system.
  2. Hot – Air: Air is heated inside the roaster or in a combustion chamber outside the roaster. The drum is not in direct contact with flames.

Distillery:

The distillery business is energy intensive. Almost ¾ of the fuel need is for firing the stills which drive the distillation process. Initially gas was used to fire stills directly beneath the pot for boiling the mash. However, it made burning and scorching a much larger concern. It also created a potential ignition source for alcohol vapours that could lead to dangerous explosions. Due to this, many stills now use gas to generate steam. Steam provides a heat in a gentle form and gives distillers greater control over the internal temperature of the mash.

Brewery:

Beer is the most consumed alcoholic beverage in the world. Though consumed chilled the making of it requires heat. LPG is used to heat boilers directly or generate steam for carrying out the brewing process. Brewers need to be able to dictate temperature so that the various ingredients in a beer react a certain way and create the required flavours.
Steam is also used for cleaning and sterilizing the tools and equipment that are used to brew. It is the best way to kill spores and bacteria that linger. In addition, steam is important for cleaning the device used to transport beer, namely kegs. Unfortunately, hot water is not good enough when it comes to cleaning kegs. If kegs are not properly cleaned, the beer created will become contaminated. Without steam from the boiler, one may have to settle for using chemical cleaners, which can get the job done but aren’t ideal.

Other Uses

LPG radiant heaters ensure that sheds and brooder houses heated to the optimum temperature which in turn influences feeding, sleeping, weight gain and feathering. It powers hot water pressure washers which are used to sanitize pens, machinery and other farm equipment. This promotes health of the poultry and prevents the spread of diseases.

  1. LPG Foggers: The device uses LPG to vaporizes the insecticide. It sprays it out fog killing pests, leaving a safe environment for the crops to grow.
  2. Weed Flamers: Weeds reduce farm productivity as invade crops, smother pastures and in some cases harm livestock. LPG – fuelled weed flamers transfer heat to weeds over a short exposure time. The flame does not burn the leaves or does it disrupt the natural photosynthesis process. The weeds wither off in a matter of 2 seconds without injury to the crops. LPG burners are also used to destroy post-harvest debris and create a sterile seed bed for the following crop.
  3. Fork Lift Trucks Powering: Diesel, electricity and LPG are regularly used to power forklift trucks. However, LPG forklift trucks are the best alternative. They produce low emissions and can be used anywhere, including food and other hygiene sensitive environments.
  4. Greenhouse: Heating is one of the most important factors to consider when growing vegetations in a greenhouse. Without sustainable heating systems in place, the vegetation can be damaged or suffer growth retardation. LPG gas heaters are designed and manufactured for safe operation in moist greenhouse environments. They burn efficiently to radiate heat and provide growth-enhancing CO2.
  5. Frost Protection: Each year millions of acres of fruit orchards, vineyards and other crop fields risk being subjected to freezing temperatures. LPG heaters are used because of their portability and ability to provide powerful heat with a smaller environmental footprint.
