The perfect filling of croissants or of other pastry products is possible due to the horizontal injection machine model DI with volumetric cylinders, designed to fill with creams, jams and chocolate also under controlled temperature. The frame of the DI injection machine consists of a conveyor with inclined platens and of a horizontal moving depositing head. In the case of highly automated lines it is possible to provide an automatic product loading and unloading system so as to restrict contact by the operators to a minimum.
The conveyor platens have been designed to hold products of different sizes and therefore reduce the time for change-over. The depositing head is driven by servo-motors to control the filling amount and distribution inside the product for absolute precise deposit. As for other Comas machines with multiple cylinders, in this case it is also possible to provide the no product – no filling option: if a product is missing during injection, the corresponding cylinder will automatically shut off the deposit. In this way the conveyor will not get dirty and production will not come to a stop.

The COMAS vertical injection machine model DT is a machine specific for the filling of loose products, made possible due to a special conveyor with indented platens. Products like croissants, cream puffs or choux buns can be filled. The frame of the DT injection machine consists of an intermittent conveyor on which interchangeable platens are fitted and shapedto the product to fill. These platens can be easily removed to allow normal cleaning operations besides quick change-overs. The head with volumetric cylinders ensures reliability and accuracy in the injection of products. The possibility to combine automatic product loading systems is bound to the shape of the product required to be injected and this technology takes place without damaging the product and ensures correct positioning inside the indentation. For fillings dosable under controlled temperature the heated hopper version is foreseen.
Designed to wok on existing continuous running conveyors, the multiple cylinder injection machine model DF is mainly used to fill loose products coming from a tunnel or cooling spiral. The injection machine model DF is available in the versions with fixed head, or with vertical and horizontal movement. It is fitted on slides to consent quick extraction from the support frame and ease washing operations. This feature can also be used for quick change-overs to reduce production downtime to a minimum. In the case of high production capacity, it is possible to drive the depositing head motion through servo-motors. The depositing accuray is guaranteed by utilizing volumetric cylinders that can be made independent so as not to inject if the product is missing (no product – no deposit). For fillings dosable under controlled temperature, it is possible to supply the machine with a heated hopper and stirrer.
The COMAS injection machine model DP with volumetric cylinders is suitable to inject products such as cakes or cupcakes on indented baking trays. For fillings dosable at controlled temperature the heated version with product stirrer is available. The injection machine model DP is made up of a forward tray indexing conveyor which, by the use of chain push lugs, positions the trays in step for product filling. The vertical moving injection head can be driven by brushless motors capable of electronically controlling the complete product filling process. In this way a very high degree of accuracy is achieved, for both the depositing and distribution of the filling inside the product. The multiple cylinder injection head provides for every outlet to be fed by a single volumetric cylinder, and therefore ensuring maximum deposit accuracy.To cut down on machine cleaning times the automatic C.I.P. washing system is also available in order to wash the machine more quickly and effectively compared to the manual method.
The depositor model DPC meets the needs of integrating the depositing process into an existing production line, thanks to the wheel-mounted frame. The volumetric cylinders are ideal for the deposit of mixes like cupcakes, cakes and muffins. The depositor model DPC has a C-shaped frame with single side shoulder: this particular structure facilitates the inclusion of the machine into a working sequence that is actually structured, without further action on the line. The depositing concept is identical to that of other volumetric piston depositors and is described as follows: the mix fed into the hopper is aspirated by the pistons through a three-way valve. When the cylinders are filled up with the required amount, the mix is dosed by a dispenser head specific for the kind of batter used. This process guarantees very high accuracy in the dosed quantity by keeping its texture unaltered. It is possible to equip the depositing head with brushless motors to achieve high production capacity and with other optional items in accordance with the customer’s requirements.
Designed to meet the needs of high production capacity, the cookie depositor model DV is a machine that meets numerous production requirements, thanks to its depositing system studied for several types of mixes. In fact it is possible to deposit smooth mix and wire cut biscuits of fluid, whipped or stiff dough also containing solid particles (eg. chocolate pieces).
The DV depositor is provided with a special frame to be cantilevered over a tunnel oven and allow depositing directly on the oven band for those products in need of this processlike smooth mix biscuits.
The depositing head consists of a pair of motorized rollers to feed the dough mix underneath to the volumetric pumps with independent lobes (one for every outlet), which deposit the product with accuracy across the whole working width. The feed rollers and the lobe pumps are both driven by servo-motors for maximum control over the depositing process. There are two pairs of independent servo-motors to also drive the vertical and horizontal movements of the depositing head, by drastically cutting back in this way on mechanics, making the machine perform better and facilitating installation over an existing oven.
The depositor model DP with volumetric independent cylinders is suitable for the deposit of products on indented baking trays. It is perfect for atters like cupcakes, cakes and muffins. The baking trays are correctly positioned in steps underneath the depositing head, by means of an intermittent chain conveyor. The depositing head with multiple volumetric cylinders can be supplied with vertical movement for dense mixes and, in the case of high dosing speeds, it is possible to have the head equipped with high performance brushless motors. Every outlet is fed by a volumetric cylinder thus always ensuring maximum deposit accuracy.
A diversity of technical solutions are able to meet with the production needs, both in terms of depositing quantities as well as of production capacity, of the single customer.
This machine model, for instance, has available a dual head to deposit products of 2 colors (e.g. marble cakes) with variable percentages of the 2 mixes according to the desired final product.
To cut down on machine cleaning times the automatic C.I.P. washing system is also available in order to wash the machine more quickly and effectively compared to the manual method.
First machine designed in 1972, the volumetric depositor model DN was the starting point for the development of COMAS piston depositors. This machine, extremely simple to operate, reliable and accurate in depositing, is used to dose delicate batter mixes like muffins and cakes in cups or moulds.
The DN depositor has a wheel-mounted frame to be fitted or moved along existing production lines with ease of maintenance and cleaning operations. The standard pneumatic-operated depositing head is driven by a single volumetric cylinder and can be supplied motorized upon request. This machine has available a range of accessories allowing to adapt to a wide variety of products, such as a heated hopper with stirrer for the deposit of chocolate under controlled temperature. To facilitate the machine cleaning process, all the product contact parts can be easily and quickly stripped down without tools
The lobe depositor model DLV is a compact and versatile machine, designed to cope with the ever more diverse needs of the market. It is indicated for the production of wire cut biscuits and smooth batters on trays and it can be used to deposit cakes or fillings as well.
The depositor model DLV is made up of a belt conveyor for trays and of a vertical moving head. The depositing system with feed rollers and individual lobe pumps ILPS (Individual Lobe Pump System) makes it possible for the machine to accurately deposit a wide range of fluid, dense and whipped mixes, also containing small solid particles (eg. pieces of nuts, chocolate).
All the machine functions are PLC controlled and the working parameters relating to every product are easily programmable by the operator on an interface panel provided and storable for quick retrieval. The DLV depositor complies with the current standards of sanitation and security: the hopper, feed rollers, lobe pumps and nozzles can be easily stripped down to consent thorough cleaning while the main structure can be washed down with water jet; all the moving parts have protection guards in stainless steel with safety switches.
