TABLE OLIVES PROCESSING 3: CANNING LINES

Totally automatic canning lines for cans and jars are used as the standard in many countries, such as Spain, specially since the 1990´s, where the labour cost has forced the substitution of manual machines for automatic ones.These lines have an average output of 300 units per minute, and in case of the highest level of automatism, it needs only 6 persons to be operated.Among the key machinery needed to provide this level of automatism are:

- Automatic depalletizers of cans and jars, where the worker simply places a pallet full of empty cans inside the machine, and the machine disposes the cans in a row inside of the canning line.
- Automatic palletizers of boxes and trays, where the finished boxes are pushed inside the machine, and the machine loads the pallets, even wrapping them when they are full.
- Automatic machines for grouping, carton boxes and trays filling and shrink wrapping cans and jars. In these machines, sealed and labelled cans and jars are pushed inside the machine, and they get out forming boxes or trays.
- Lineal pasteurizers, discontinuous autoclaves. In this last case, and in order to create a continuous line with this non-lineal machine, YARKI designs automatic equipment for baskets loading and unloading.

For a lower level of automatism, and an average output of 150 units per minute, some of these machines are substituted by semiautomatic machines. In this case the initial cost of the line is quite lower, but the operation cost are higher. YARKI adjusts their TURNKEY lines to the client demands, taking into consideration factors such as the labour cost of a particular region.
Regarding to the plastic bag canning lines and canning in vacuum or inert gas protection, YARKI designs these lines with automatic equipments, except for the boxes filling process, which is usually made by hand in special boxes forming tables. These tables are designed according to the main machine capacity (bags filling machine).

TABLE OLIVES PROCESSING 2: CALIBRATING, OXIDATING, PITTING

CALIBRATING LINES

Except for small capacities, these kinds of lines are totally automatic nowadays. They include electronic selector machines. These machines have standard capacities for 3.000 Kg/h, substitute a big number of workers and make the sorting (it separates 3 different kind of qualities) with a better precision and guarantee.

The full line includes hopper with elevator, stemer machine, electronic selector machine (or selection belts) and calibrating machine. The calibrating machine must be chosen according to the calibres and the foreseen capacity, which uses to be 3.000 Kg/h in this kind of lines.

OXIDATION LINES

Oxidation is a discontinuous process, which takes place in PRFV horizontal tanks of a capacity between 5 and 10 tonnes of product.The needed time for the complete oxidation of the olives varies between 3 and 5 days. The additional equipment necessary is the rotative air blower with the adequate capacity, and the piping system needed for the automation of the process.

PITTING, SLICING, STUFFING LINES

At present, the trend is to level the production speed of this line with the canning line, connecting both of them. Therefore, several pitting machines are disposed in the line in order to match at least the canning line standard capacity for the chosen format. The pitted or stuffed olive goes through a densimeter and a washing machine, and after the inspection, they go straight to the canning line. The pits are transported by underground piping to a storing tank, with the help of special pump and water circulation circuits.

There is a high variety of stuffs at present and it is very important to note that the filling machine of the canning line to be designed not to produce damage in the stuffed olive.

TABLE OLIVES PROCESSING 1: RECEPTION AND FERMENTATION

RECEPTION OF FRESH OLIVES
The design of these lines is conditioned by the foreseen capacity and other factors such as the ripeness of the olives, or the harvesting technique.
YARKI usually designs automatic lines with electronic sorting machines, which have nowadays reached a high level of technology and reliability when high capacities are required (more than 10.000 Kg/h).
The standard line comprises reception hopper, machine for removing the branches, turbine for removing the leaves, precalibrating machine for removing earth material and not commercial sizes of olives, inspection belts (or electronic sorting machine) for separating green, purple and black olives, and treatment tanks for treating with soda the olives before sending them by gravity to the underground fermentation tanks.
The standard capacity of these lines is between 10 and 20 tonnes per hour.



FERMENTATION OF GREEN OLIVES
The cost-effective solution for the fermentation and storage of the olives are the big PRFV tanks (Polyester Reinforced with FibreGlass). Their capacities range between 16 y 22 m3, and they can be aerial or underground tanks.
In this case, our services are centred on:
- The chemical composition of the tanks (adequate materials for food applications, bearable load, and long-life of the tanks).
- Co-ordination of the shipping, choosing the best freight.
- Quality control of the assembling (using adequate materials, drying resin under atmospheric conditions, pores inspection and permeability tests.)
- Project and management of the civil works (pit, drainages, foundation of the tanks, levelling, burying, compacting, sealing...)
