Rapeseed Meal extract or meal is a derivative from rapeseed oil manufacture. It is created from the pressing of seeds used to extract oil from the plant, generating a byproduct of rapeseed meal – a dry, sludgy residue that can be viscous. It can be repurposed as a soya replacement for protein which can in turn reenter the supply chain as feed for animals or used to alter the fatty acid composition of milk.

An agricultural processor contacted us who were looking to reuse and recycle large amounts of rape meal as a way of generating an income stream from waste, as well as work towards meeting net zero and sustainability targets.

During cold oil processing they found large amounts of meal was being generated, which was not being utilized efficiently. The meal was gathering in pits, or containers with water and the customer wanted to transfer it quickly across their plant into easily transportable containers such as IBCs for resale and transport. There were various sources of the meal, and they wanted the ability to move a pump kit between various points to easily decant containers or empty pits of the liquid.

North Ridge worked closely with the customer to fully understand the full application data such as the distances in which the fluid would be pumped, the liquid characteristics and solid concentration and viscosity.

It is important to understand the nature of waste liquids as quite often its consistency can vary between operations making it difficult to transfer as it can be viscous, be highly abrasive solids which can quickly wear pump working parts or seals and clog within units. We can usually quickly determine what pump may be best for an application or which technology may be best suited for a particular fluid often by seeing pictures or videos of the fluid being poured, stirred or agitated without having to wait for an engineer to visit site.

We specified and supplied a self priming mobile pump kit which could be used to draw the fluid located in tanks below the pump, or take the liquid directly from vessels transferring it up to 10M horizontally and 6M vertically. We worked with the customer to ensure the process water could be pumped at its processing temperature – 50°C without waiting, as well as handle the suspended solids which were up to a few mm in diameter. The pump was supplied with a local on off switch for ease of control and a 10M 3 phase power cable.

Utilising a pump kit not only enables operators to work more efficiently and recover waste product but they can be designed to eliminate manual handling, and automate fluid transfer. Pump sets can be customised to accommodate almost any process, be made mobile for ease of portability and supplied complete with accessories for easy all-in-one fluid transfer such as hosing, flowmeters and dispensing nozzles. As North Ridge Pumps are not limited to a single pump technology, it enables us to specify more than one solution for your particular process, and handle virtually any kind of fluid.
