A Pig Abattoir refers to a place where pigs are slaughtered for meat. Several types of pig abattoirs are prevalent around the world.
Farm-based abattoirs
On small-scale livestock farms, slaughtering facilities may be located on-site. These zootecnic abattoirs are designed primarily for local consumption and are often subject to less stringent regulations than larger commercial facilities. As a result, they typically feature simpler setups with basic equipment alongside experienced personnel who know how to handle animals properly during the slaughtering process. Moreover, these kinds of abattoirs have been known to reduce stress levels in animals by minimizing transportation time, thereby resulting in higher quality meat products.
Mobile abattoirs
Mobile abattoirs are units that have been designed to be transported from one location to another. They provide an efficient way of slaughtering animals closer to where they were raised, thus reducing transportation stress for livestock. This innovative solution helps farmers better manage their operations while also improving the quality of meat products. Mobile abattoirs can take on various forms such as trucks or trailers equipped with all necessary facilities and equipment needed for handling, processing, and packaging meat.
Custom abattoirs
Custom abattoirs are facilities that slaughter animals for individual farmers or business owners. The process is tailored to the specific client's needs, including how the animal should be handled during slaughter and any special processing requests. This can involve producing specialty meats such as organic or grass-fed beef, which requires additional certifications and procedures to ensure quality standards are met. Custom abattoirs may also offer personalized butchering services where customers can choose certain cuts of meat and have them cut exactly as requested. These kinds of abattoirs provide a valuable service to small-scale farmers who cannot afford large production amounts but still want access to commercial-grade meat processing facilities.
Pig abattoirs include many small slaughterhouse machines, each requiring its specifications.
Horizontal pig stunner
The horizontal pig stunner is an important part of the pig abattoir. According to the workload, its power range is 2-5 kw. To meet the slaughter needs of different places, the length of the stunner also has a certain degree of flexibility. The stunning method can use a 12-24 volt battery or 220-240 volt AC supply.
Bleeding cradle
The pig bleeding cradle is made of 304 stainless steel. Its design conforms to the ergonomic principles. Its adjustable parts can adapt to different sizes of livestock, thus ensuring the stability and safety of animals. This prevents secondary pollution during the slaughtering process. Its length is usually 1500-4000 mm. The size and capacity are negotiable.
Skinning machine
Skinning machines(also called pig skinner cradle) are available in manual and electric options. While hand-operated machines are more affordable, they require greater physical effort. Electric skinning machines save energy but consume electricity. Skinning machines come in a size range from small to large, as shown below. The larger the machine, the more capacity it has for handling pigs per hour. For instance, one could have a small electric skinning machine that would skin one pig at a time. Another larger pig skinner could skin up to 20 pigs per hour with more capacity.
Manual skinning machine Size: 1900*700*1300mm capacity: 2-4 pigs/hour
Electric skinning machine Size: 2400*1150*2350mm capacity: 12-15pigs/hour
large skinning machine Size: 2400*1450*2700mm capacity: 18-20pigs/hour
evisceration cradle
The pig evisceration cradle is also made of 304 stainless steel. Like the bleeding cradle, it conforms to ergonomic principles and can be cleaned easily. Its dimensions include lengths of 1500-4000 mm. The size and capacity are negotiable. Pig evisceration cradles are essential for properly removing the internal organs of slaughtered pigs. They provide a secure and controlled environment for this process, minimizing the risk of contamination and facilitating accurate organ extraction.
chilling tunnel
In an abattoir, a pig carcass is often placed in a chilling tunnel after it has been skinned and eviscerated. A blast of cold air is used inside the chilling tunnel to cool the carcass, improving its shelf life. Some chilling tunnels use ammonia as a refrigerant while others use carbon dioxide. The ammonia chilling tunnel has a plate heat exchanger, evaporator, ammonia compressor, and condenser. The carbon dioxide chilling tunnel uses a CO2 compressor and a heat exchanger.
Pig slaughter conveyor
A pig slaughter conveyor is an important link in the slaughtering process. There are two main types: the chain type and the hanging type. They are all made of stainless steel. The speed can be controlled to ensure the timely processing of pigs and the efficient flow of work. On average, a pig processing conveyor measures 3000*600*1000mm.
Pig cutting saw—
Generally speaking, pig cutting saws come in two types: hand-held and electric. The electric saws usually have a 2.5 to 3.5 horsepower (hp) motor with a 110v or 220v/50hz-60hz power supply. The cutting blade length ranges from 1200 mm to 1400 mm. It is important to understand that safe and accurate pig cuttingrequires a pig cutting saw with a comfort grip handle and a guard. The cutting saw also needs to have a lighting system to ensure better visibility when slaughtering pigs.
Pigtail conveying system
Also called pig conveying system, its length can reach 4000 mm or more. It is made of 304 stainless steel and designed in accordance with ergonomic principles. The pigtail conveying system is a crucial element of the pig slaughtering line. It transports the carcasses after the pigs have been slaughtered, skinned, and eviscerated. The system can be used to convey carcasses in the cooling, processing, or packaging areas, which improves workflow efficiency.
Cleaning and maintaining the pig abattoir machine are important for food safety, hygiene, and equipment longevity. Regular cleaning can help prevent the spread of disease, contamination, and infection. On the other hand, it can prolong the machine's lifespan by keeping it in good condition and minimizing wear and tear.
A pig slaughtering machine can be cleaned and sterilized easily with a pig slaughter machine kit. This slaughtering kit usually comes with a washing and cleaning kit. It will include knives, tools and their cleaning supplies.
When getting ready to clean and maintain a slaughtering machine, it is important to read the manufacturer's manual and follow their instructions. Health and safety laws on proper slaughtering and butchering should also be studied and adhered to during this process.
Before starting the maintenance process, it is essential to carry out a risk assessment. Identify the hazards associated with the slaughtering kit that may arise during its use and when carrying out maintenance. Carefully determine and assess the potential health and safety risks, including those that are manual handling and process related.
With the proper slaughtering kit and appropriate cleaning solutions, the slaughtering machine can now be cleaned. Dismantle the parts of the machine and then clean and sterilize the slaughtering machine thoroughly, ensuring that no part is missed.
