How To Deal With Grease Produced From Spit-Roasting Ovens?A catering or food business is one of the most thriving industries which is never going to experience a recession. But the owners of the food business know it well that all the profits depend on good maintenance and management of the core operations involved. One of them is the heart of the food establishments – their commercial kitchens. There is a long list involved when it comes to proper maintenance of the commercial kitchens. One of them is the maintenance of the heavy-duty equipment like the spit-roasting ovens and their associated grease traps – if you have one.

Spit-roasting is a technique used since the medieval period. The method was popularly used by big households. However, the modern spit-roasting oven also known as Rotisserie was first introduced by the Boston market in the restaurant industry. Soon it became popular and owners of food establishments around the world followed the trend in their commercial kitchens.

The Working Of Spit-roasting Oven

Well, it is interesting to know that Rotisserie ovens use a slow style of roasting using a spit where the meat is skewered over a fire or in the oven. Spit is a long solid rod that holds the meat to be cooked in place. Based on the type of meat roasted, two kinds of spit-roasting ovens are used – vertical and horizontal. The method is generally used to cook large joints of meat or even the entire animal like chickens, turkeys, and pigs. A slow rotation process is involved during cooking, which ensures the meat is cooked from all sides evenly – resulting in a hearty tender feast for the foodies.

From the maintenance point of view, spit-roasting ovens can present a challenge for the commercial kitchens and the municipal sewer systems. How? Let us look into the context below.

Importance of Grease Traps In Rotisserie Ovens

Rotisserie ovens are used just for one purpose – meat roasting. As the meat roasts, fat and juice run down and get collected in a pan at the bottom of the oven. When the size of the oven is small, this pan can be emptied manually. But when huge spit-roasting ovens are used in commercial kitchens, then managing grease manually becomes a difficult task. Therefore, in commercial kitchens, ovens are connected to a supplemental water line. At the bottom of the oven, water flows into a shallow “bath”. Further, the oil and water flow down into the grease trap unit preventing FOG from entering the sewer system.

Hence, it is important that a grease trap is installed for a spit-roasting oven. Grease interceptors for oven work in a similar manner to other conventional grease removal units for under sinks and basements.

How To Decide The Size Of Grease Trap For Your Rotisserie?

Considering the size of the grease interceptor unit is crucial. For, if you choose an inappropriate size, the unit will not work efficiently. For example, if a smaller unit is installed, it can reach the capacity and hence not be able to stop the fats, oils, and grease from entering the drainage system.
The size of the grease trap that is to be installed with oven depends primarily on three factors which include:


The amount of meat roasted varies from season to season. Demand for hot-cooked meals tend to be higher in winters. Naturally, the amount of meat roasted during this time will increase. So, food establishments need to keep a check on the seasonal shift.

Meat roasted per day

A spit-roasting oven operating at high temperature will drip more amount of FOG. After the end of the roasting period, the oven comes down to ‘holding mode’ when the temperature is low. Depending on the use of the oven, food service owners can calculate the time when the production of FOG from the oven is high.


Of course, menu significantly matters. If you own a purely non-vegan restaurant your oven is ought to produce a high volume of grease. For that, you need a high capacity grease trap. But if you have a mixed menu (vegan and non-vegan) then you may need a smaller capacity grease trap.
Furthermore, a small spit-roasting oven that cooks upto two chickens is likely to produce half a cup of grease. And if it goes beyond 10 to 15 birds, it is most likely to produce five to seven cups of the greasy stuff. Whereas a heavy-duty oven that is used in large commercial kitchens generally roasts more than 70 chickens at a time. Such ovens produce over 70 pounds of grease which definitely needs a high-capacity grease trap to capture the FOG. Therefore, choose the correct grease trap for your spit-roasting ovens to reduce your plumbing cost.

Easy-To-Maintain Grease Traps For Spit-roasting Ovens – From Grease Guardian

Grease Guardian offers a highly sophisticated yet easy-to-maintain grease trap tailor-made for spit-roasting ovens. The speciality of these grease removal units lies in the fact that they are equipped with automatic features that take care of the operations seamlessly.
The operation of the unit starts with the collection of the FOG from the oven into a supplemental water line. From there the FOG is directed towards the unit containing a strainer basket that collects solid food waste. Then the FOG separation process begins where the oils and grease float to the surface allowing the treated wastewater to flow into the sewer system. This is followed by the self-cleaning and grease removal process where a heating element liquefies grease. The liquid grease is removed through a skimming wheel and disposed of in a portable container for recycling. This unit from Grease Guardian is also outfitted with an automatic spray system that cleans the grease trap and refills the water level for constant skimming of grease.
