Description
Extrusion process, apparatus and product
The present invention relates to an extrusion process for the manufacture of cooked cereals or dry pet food, an apparatus for carrying out the process and a product obtainable by the process .
US5997934 (Geromini et al . ) discloses a process for the manufacture of cooked cereals or dry pet food which comprises preparing a mixture of water and a dry premix mainly comprising cereal flour or semolina,' cooking the mixture and extruding it by pressing it through an extrusion die with the aid of a gear pump.
US5667833 (Juengling et al. ) discloses a process and an equipment for manufacturing pasta which comprises, preparing; a mixture of cereal flour and water having a ater content ; of 25-40%, kneading the mixture and extruding it by pressing it through an extrusion die with .the aid of a gear pump .,
The aim of the present invention is. to provide an extrusion process and apparatus which maintain the starch's molecular structure in order to manufacture a product with properties close to those of a traditional rollerr-dried product and superior to those of a traditional cooked-extruded product.
As a matter of fact a traditional roller-dried product was not subjected to any mechanical stress during its whole manufacturing process, because a traditional roller-dried product was obtained by roller-drying a cooked slurry mainly comprising cereal flour and 40-45% water, the slurry having been cooked in a vat and the drying effect being obtained by pure heat transfer from the roller to the film of slurry applied on its surface.
On the other hand, a traditional cooked-extruded product was subjected to high shear during its manufacturing process, because it was subjected to high pressure and friction while being cooked in the extruder.
The process of Geromini et al . mentioned above in fact comprises extrusion-cooking the mixture of water and flour before pressing it through an extrusion die with the aid of a gear pump .
On the contrary, the whole process of Juengling et al . mentioned above is carried out while maintaining the temperature of the mixture of water and flour or semolina below 55°C so that a raw pasta is obtained, without any gelatinization Of the flour or semolina.
The process for the manufacture of cooked cereal products or dry pet food according to the present invention comprises preparing a mixture of water and a dry premix mainly comprising cereal flour or semolina, and pressing the mixture, with the aid of a gear pump, firstly through a heat exchanger wherein it is cooked and then through an extrusion die.
Likewise, the apparatus for the manufacture of cooked cereal products or dry pet food according to the present invention comprises a mixing device, a gear pump, a heat exchanger and an extrusion die connected in series.
Throughout the present specification and claims, the expression "mainly comprising cereal flour or semolina" means comprising at least 50% or preferably at least 70% of cereal flour or semolina.
Similarly, the expression "a mixture of water and a dry premix" means "either a mixture of water and dry premix or a mixture of steam, water and dry premix" .
It has been observed, surprisingly, that it is possible with such a process and such an apparatus to maintain the starch's molecular structure in order to manufacture a cooked cereal product or dry pet food with properties close to those of a traditional roller-dried product and superior to those of a traditional cooked-extruded product.
This fact may especially be observed by comparing the •respective gelatinization degrees and starch profiles.
The degree of gelatinization indicates the efficiency of the heat exchanger and how well the product was cooked. , Typically, gelatinization of at least 85%, preferably; of 90% or more indicates a sufficiently cooked cereal. The starch profile describes the repartition of the .two! _ _.j functional molecules, of starch, a ylose and amylopectin that directly influence important properties of the final product (e.g. viscosity, texture, solubility, and., stickiness) . Mechanical stress as applied in traditional single- and twin-screw extrusion mainly destroys the amylopectin fraction thus reducing viscosity and increasing solubility and stickiness. This is why existing products made with low-shear technologies (roller drying, high moisture cooking) cannot be exactly copied by extrusion. Therefore, the present process aims to maintain the initial starch profile by reducing shear. This is the precondition to obtaining products with properties similar to those of of roller dried or high moisture cooked products.
Thus, the product obtainable by the present process and apparatus preferably has a gelatinization degree of at least 85%, more preferably of 90% or more.
It also preferably has a starch profile characterized by respective proportions of 40-70% amylopectine, 5-22% intermediates and 15-35% amylose . 5
In addition, the present product preferably has an expansion degree of from 1.5 to 10, more preferably of from 2 to 6.
10 To carry out the present process for manufacturing cooked cereals, it is possible to prepare -a dry premix comprising 70-88% of a flour or semolina of a cereal such as wheat, oat, corn and/or rice, and up to 2.0% of sugars such as sucrose and dextrose, to which other traditional
1.5 ingredients may be added such as up to 2%. of sodium chloride, up to 8% of oil or fat such as vegetable oil or fat -or butter, oil, up to 15% of modified- starches such as i modified corn or. wheat starches, up to .10% of powdered milk or other protein source, up to. a few % of. cocoa 0 , powder, up to a few % of malt,, up to 0.5% of mineral salts, up to 0.5% of vitamins, up to 2% antio'xidants, and possibly even enzymes which can reduce the viscosity of the mixture to be prepared, for example .
5 For manufacturing dry pet food, it is possible to prepare a dry premix comprising at least 50% of cereal flour, 25-35% of meat flour and animal by-products, 5-15% fat and tallow, up to 10% vegetable by-products and up to 6% vitamins and minerals, for example. 0
For manufacturing either cooked cereals or dry pet food it is possible with the mixing device to prepare a mixture of water and the premix such that the mixture has a water content of 12-45%, preferably of 12-30% and more 5 preferably of 12-22% by weight.
The still un-cooked mixture is then pressed into the heat exchanger with the aid of a gear pump .
To this end the gear pump may be fed with this mixture in a continuous, steady way, while exerting on it a relatively low pressure of the order of from about 100 to 2000 kPa upstream of the gear pump, for example.
It is then possible to have the gear pump exerting a pressure of from 3000 to 25000, preferably from 4000 to 20000 and more preferably from 5000 to 16000 kPa on the mixture upstream of the heat exchanger.
Because the residence time in the gear pump is short and the mechanical energy input is low, the original raw materials may reach the heat exchanger without any major molecular degradation.
It is possible to cook this mixture by progressively heating it to 90-180°C, preferably to 100-160°C for 2 to 15 min along the heat exchanger, for example.
The cooking in the heat exchanger occurs by mainly thermal heat transfer thus maintaining the original molecular structure. The properties of such a cooked product will be close to that of a traditional roller-dried product and superior to that of a traditional cooked-extruded product.
In order to press the mixture through said extrusion die, it is possible to maintain a pressure of from 2000 to
10000, preferably from 3500 to 9000 and more preferably from 4000 to 8000 kPa downstream of the heat exchanger and upstream of the die. The pressure loss accross the heat exchanger may be between 1000 and 20000, preferably between 1000 and 17000, and more preferably betweeen 1000 and 12000 kPa.
It is possible to cut the extruded rope of cooked mixture thus obtained into pellets or puffs just at the exit of the die with the aid of a cutting device, for example.
As to the present apparatus, the mixing device may be a high speed blade mixer, a twin-screw intermeshing and corotating mixer or extruder, or a single-screw extruder, for example .
The heat exchanger preferably is a static mixer heat exchanger. The static mixer may be of any adequate type such as the one disclosed in US5486049 (Boatman et al . ) or US5538748 (Boatman et al . ) or those equipping standard SULZER tubular heat exchanger such as SULZER's SMR DN80 type static mixer heat exchanger, for example.
The gear pump may comprise two toothed wheels, or toothed rollers which mesh with each other. The two rollers can rotate in a housing on axles situated iri a plane' perpendicular to the direction of a mixture stream. They can each rotate in the opposite direction, the teeth coming apart upstream and closing again downstream. The outer edge of the teeth can slide against a corresponding inner wall of said housing, thus defining intersticial spaces intended for transporting the mixture to be extruded downstream. The shape of the teeth may be especially designed to avoid as much possible any shearing on the mixture .
The extrusion die may comprise one or more extrusion conduits, especially cylindrical conduits, generally oriented in the same direction as that of a stream of cooked mixture to be extruded, for example. The shape of the extruded rope may be determined in particular by the shape of the outlet opening or orifice of said conduits.
The cutting device may be a rotating knife, for example.
Embodiments of the present apparatus are described below by way of example only with reference to the accompanying drawings in which:
Figure 1 is a schematic view of an embodiment of the present apparatus, - Figure 2 is a schematic view of a heat exchanger static ;mixer which may be used in the ■ embodiment of the: apparatus represented in Figure 1, and

For carrying out the present process, the mixer 1 may be fed with the different components of the mixture through hopper 6. At a downstream end of the mixer 1, a still uncooked but homogeneous mixture may be obtained. The gear pump 2 may be fed with this mixture in a continuous, steady way. The mixture may be pressed by the gear pump 2 firstly through the heat exchanger 3/4 (under the effect of a pressure p2 exerted upstream of the heat exchanger) , where it is cooked, and then through the die 5 (under the effect of a pressure p maintained downstream of the heat exchanger and upstream of the die) .

The mixture was pressed by the gear pump through the1-hea exchanger under a pressure p2 of 10900 kPa. The static mixer of the heat exchanger were heated to' a temperature of 150 °C with high pressure water. The mixture was thus cooked by having it heated to 118 °C in a few min through the heat exchanger. " ' ~ I
The pressure loss along the heat exchanger was 5500 kPa so that the mixture was then pressed through the die under a remaining pressure of 5400 kPa .
The product thus obtained had a gelatinization degree of 93.3%.
The product had a starch profile characterized by respective proportions of 57.9% amylopectine, 20.7% intermediates and 21.4% amylose.
Example 4
The same apparatus was used as in Example 2
A mixture having a water content of 20.3% was prepared in the mixer which was fed with 57.1 kg/h of a premix comprising 55% rice flour, 28% corn semolina, 13% sugar and
malt and 4% cocoa powder, 7.9 kg/h of water and 2.3 kg/h of oil .
The mixture was pressed by the gear pump through the heat exchanger under a pressure p2 of 13500 kPa . The static mixer of the heat exchanger were heated to a temperature of 150°C with high pressure water. The mixture was thus cooked by having it heated to 121°C in a few min through the heat exchanger.
The pressure loss along the heat exchanger was 6000" kPa so that the mixture was then pressed through the die under a remaining pressure of 7500 kPa .
The product thus obtained had a gelatinization degree of 85% and an expansion degree of 1.5.
The product had a starch profile characterized by respective proportions of 51.6% amylopectine, 20.2% intermediates and 28.2% amylose.
Comparative example
For the purpose of comparison with the product obtained in Example 4 a comparative sample was produced from the same starting mixture but using a BC72H type CLEXTRAL twin-screw extruder instead of the present apparatus .
The extruder was provided with a die in form of a steel plate provided with six cylindrical conduits each having a circular outlet opening 3 mm in diameter.
The extruder was fed with about 3.5 times the amount of starting mixture with whom the mixer was fed in Example 4.
The extruder barrels were heated to achieve the same product temperature as in the SULZER heat exchanger.
The comparative product thus obtained had a gelatinization degree of 84%.
The comparative product had a starch profile characterized by respective proportions of 28.3% amylopectine, 48.3% intermediates and 23.4% amylose.
/Thus the relatively low proportion of amylopectine" remaining in the comparative product and the relatively high content in intermediates found in the comparative product stood in surprisingly stark contrast with the relatively high proportion of amylopectine maintained in ;he product of Example 4 and the relatively low content in intermediates found in the product of Example 4.
