When fresh fruit becomes not practical and convenient, because it is less available at certain latitudes and in certain seasons, or because the consumption situation makes preparation difficult, the ready alternative of processed fruit comes to our aid.
To produce fruit based preparations, for instance peach or apricot based, we need a production line organized in different processing stages, and one of these is removing the pit, which is called “pitting”.
WHAT IS INDUSTRIAL PITTING?
Industrial pitting consists of the automatic removal of the fruit pit, through the aid of an industrial machinery capable of processing several fruits at once, and it is one of the most important phases to process, for instance, a timeless and always useful product such as canned peaches. A typical processed fruit production plant has a row of pitters of different “formats” (the fruit size) installed along the process line. Industrial pitting can be classified in the different systems “spoon”, “torque”, “repitting”, “coring”. We proceed now to analyze more in detail these technologies.
HOW DOES PITTING WORK?
Spoon peach pitting is carried out by means of a couple of flat knives that split the fruit in two and a couple of spinning spoons that parts the pit from the pulp. It is the most convenient system for big production volumes, because the machine capacity is higher compared to other systems.
Torque pitting employs a mechanical grip system that parts the pit from the pulp through inverse rotation of the two peach halves. It has a lesser capacity but a higher yield, in terms of amount of pulp in the final product versus product waste.
When the industrial pitting process cannot remove the pit, which is still attached to the half peach pulp, we need a repitter, which reprocesses on a conveyor belt the half peaches with the pit attached and removes the pit through a knife specifically designed for the purpose.
The Coring application was designed to output a top quality final product (Zero Pit Fragment Tolerance) destined to the Baby Food sector, because the machine removes the whole cylinder section containing the pit, preventing fragment production altogether.
OUR INDUSTRIAL PITTERS
CTI FoodTech offers the most performing spoon pitters on the market, because they can maximize capacity, that is the number of fruits processed per minute, and at the same time reduce costs of operation, virtually eliminating need for manpower, and considerably reducing maintenance costs.
The spoon pitter model 320 APA processes 320 fruits per minute and is equipped with an internationally patented continuous orientation system, which eliminates need for additional manpower previously employed for the fruit orientation operation.
The model 320 APA-E is the electronic evolution of 320 APA and has a capacity of 336 fruits per minute, thanks to the brushless motor controlled by a PLC, as well the orientation system already implemented on the model 320 APA.
The model 350 APA-Vision can orient correctly over 95% of fruits with no need for manpower, thanks to a patented sophisticated optical scan and robotized handling system, that recycles in the machinery the fruits that failed to pit because they were not correctly oriented.
The CT800 pitter is the torque model offered by CTI FoodTech. With a capacity of 82 fruits per minute, the CT800 is more performing compared to the models of competition and requires less maintenance.
CTI FoodTech offers three models of repitter: the Repitter 6219, the Repitter Vision and the Repitter Slim.
The model Repitter 6219, capable of repitting 320 peach halves per minute, is equipped with an automatic aligning system and a spoon repitting system that minimizes reprocessing time. The machine is designed to ease maintenance, reducing costs.
The model Repitter Slim has the technical features of the Repitter 6219 with a capacity of 160 halves per minute, for plants with a lesser production volume.
The MultiFruit Coring is designed to output fruit high quality fruit halves destined to the top segments of the food market.
The Avocado Pitter 300-AVC is the first machine in the world capable of pitting the avocado. Before this machine was introduced, the pitting phase of avocado processing at all canning plants around the world was carried out exclusively by hand. This made the process significantly slower and less profitable in terms of labor employed and productive capacity.
The latest tendencies in nutrition science place the avocado in the highest ranks of premium healthy food, because of its nutritional value as well as its unique taste features. As a result, its potential market is quickly expanding and so is the number of plantations.
In order to tap into this growing market, CTI FoodTech developed a specific study on the avocado pit and devised a technique to act from within the fruit and remove it without breaking it. CTI FoodTech designed a machine that enables the fruit, fed randomly, to be sorted, sequenced and pitted at a speed of up to 300 avocados a minute in a fully automatic way, needing no labor.
