Thanks to our technical know-how and engineering expertise, we have been able to design turnkey plants.
The OLEXA® team design, manufacture, install and start the equipment necessary to setup a “Greenfield” project.
As part of our engineering services, we can also provide the following documents:
- A site plan for equipment installation, including general building dimensions
- A flow diagram showing equipment, energy used and tracking (Machines, motors, sensors)
- A list of forecasted energy consumption (electricity, steam, compressed air)
- A list of discharges (steam conditioner)
- the foundation plans for each type of equipment including floor installation and technical data (mass, seal type, connections etc…)
- The overall plans for steel structures, machine supports, handling supports, nozzles (the latter is not provided and is only covered in the plans)
- a diagram of plumbing principles: steam and condensate (conditioner), oil circuit (filtration), press fume extraction up to the outlet flange or even a complete study of the pipes (procurement and installation of equipment would be your responsibility)
- Detailed drawings (isometrics) of all pipes with parts lists
- Pipeline list
- Calculation note according to the European Pressure Equipment Directive
- Pipe measurement (lengths, number of elbows, reductions, etc.…)
- Production of a 3D model
- Support study
- List of techniques (sensors, motors, length and type of cables, etc.)
- Schemas of electric automation and power cabinets.
- Equipment manuals in local languages.
Our team will be happy to accompany you on a complete process or regarding individual equipment:
The crusher with smooth or corrugating rolls will allow you to mechanically prepare the seed before cooking The main component of each such unit is the crushing system itself (set of rolls or rotor/stator with blades) which may be associated with a feeder. Both are positioned and guided between two frames by a set of bearings. The power required for crushing is provided by a main control unit. The required feeder is equipped with its own drive unit.
Everything is aligned and clamped onto a chassis through which the crusher is set up in position to start work. Different housings and metal structures complement the device.
Horizontal and vertical cookers
The thermal conditioning of oleic products is of great importance in the field of crushing, when it comes to extracting the oil by pre-pressure and more particularly by single pressure.
The function of conditioning is to pre-treat the oleic cells of the materials in order to promote the separation of oil from the “dry” matter.
Accuracy in thermal conditioning leads to higher quality of extraction by screw press.
We design and manufacture horizontal and vertical cookers.
The horizontal cooker is a tubular device with a double envelope inside which operates a paddle rotor designed to ensure that heat is applied evenly and also adequate agitation of matter. The rotor is driven by a geared motor group located on one of the flanges of the device. The vertical cooker is mainly composed of a vertical cylindrical body. Installed inside this body are the heating plates which make up the various stages of the device. Mixing arms are securely fastened onto a vertical shaft and move inside during each of the distinct stages. This assembly is rotary driven by a geared motor unit mounted at the upper or lower part of the apparatus, depending upon implementation.
- The screening tank deserves some particular attention in the field of separation of oils, fats and all products that can be subjected to static decanting. Indeed, it allows further separation of sediments :
- to be connected directly to one or more screw presses;
- to fit perfectly into a sediment recycling circuit;
- to be able to house a device for dewatering press feet.
The screening tank has the following features:
- Static decantation;
- Continuous separation and evacuation of sediments;
- Liquid phase storage;
- Alleviates workload on devices used at final clarification stage;
- Integrated continuous spinning (optional).
- The screening tank consists of a parallelepiped tank in which scrapers turn by means of conveyor chains. Strictly speaking, the separation is carried out via drainage upon a fixed grill attached to the upper part of the apparatus. At the end of this one, a trough collects the solid products and a screw evacuates them.
Filter plates or vertical plates
We offer sediment bearing oil filters with either:
- Filter plates with manual cleaning
The filter plates consists of a set of trays between which polypropylene fabrics or papers are interposed and act as a filtering element.
Each tray has two exterior ears which allows it to be placed, before tightening, on two longitudinal supports. The tightening of the stack is achieved by means of two retaining nuts sitting at the same level as the supports.
The sealing of the assembly is ensured by the filter plates themselves, during tightening. This is achieved regardless of the pressure and the number of plates used.
- Automated vertical filters.
The vertical filter consists of a cylindrical tank, made in thick sheet steel. At its upper part, the filter has a cover with a locking mechanism using tipping bolts and an opening system driven by a manually operated hydraulic cylinder, giving access to the filter elements arranged inside the tank.
The different filtration steps can be managed by means of motorised valves installed on the device and returning information to the plant supervisor system.
