Opfindelsen angår en osteform til brug ved fremsti 11ing af oste. Under fremstillingen af oste anbringes osten i en presseform, der er en åben kasse, hvis sider, låg og bund er perforeret. Ostemassen udsættes for et presse- 5 tryk, der for de hårdest pressede oste typisk er ca .The invention relates to a cheese mold for use in the manufacture of cheeses. During the making of cheeses, the cheese is placed in a press mold which is an open box whose sides, lids and bottom are perforated. The curd is subjected to a pressing pressure, which for the hardest pressed cheeses is typically approx.

2 0,4 kg/cm til udpresning af vallen i ostemassen.2 0.4 kg / cm for squeezing the whey into the curd.

Formene skal således have en mekanisk styrke, der kan modstå pressetrykket.The molds must thus have a mechanical strength that can withstand the compressive pressure.

Et andet forhold, der gør sig gældende er, at tempera-10 turen ikke må komme under et bestemt temperaturinter-val . Således holdes rumtemperaturen på 32-36°C.Another factor which is concerned is that the temperature must not fall below a certain temperature range. Thus, the room temperature is kept at 32-36 ° C.

For at osten ikke skal miste sin form henstår den i ca.For the cheese not to lose its shape, it is left for approx.

36 timer i en form. Dette kan være den presseform, som osten er blevet presset i. En anden mulighed er at af-15 forme ostene og at anbringe dem i en holdeform, der er en form, der blot holder ostens form. Den er således ikke dimensioneret til at optage det store pressetryk ved udpresning af vallen. Derved sparer man i investering til et større antal presseforme.36 hours in one form. This may be the pressing mold in which the cheese has been pressed. Another option is to deform the cheeses and to place them in a holding mold which is a mold that simply holds the cheese's shape. Thus, it is not designed to absorb the large compressive pressure when extruding the whey. This saves you investment in a larger number of press forms.

20 Oprindeligt anvendte man trækasser beklædt med klæde som osteforme. Der er nogle specielle ostetyper, hvor man fortsat anvender disse trækasser. Mest udbredte er nok rustfri stålforme, der kan modstå det store pressetryk. Man har eksperimenteret med at lave osteforme af 25 plast, eksempelvis af polyethylen. Kasserne laves som en ganske almindelig kasse med glatte overflader. For at kunne modstå pressetrykket har det imidlertid været nødvendigt at have en overordentlig stor godstykkelse.20 Initially, wooden boxes covered with cloth were used as cheese molds. There are some special cheese types that continue to use these wooden boxes. Most prevalent are probably stainless steel molds that can withstand the high pressure. Experiments have been made in making cheese molds of 25 plastics, for example polyethylene. The boxes are made as a fairly ordinary box with smooth surfaces. However, in order to withstand the pressure of pressure, it has been necessary to have an extremely large thickness of goods.

Det bevirker imidlertid at det er umuligt at perforere 30 formen. Dette er nødvendigt for at dræne vallen væk.However, it makes it impossible to perforate the mold. This is necessary to drain the whey away.

Man har løst problemet ved at lave nogle store udsparinger på formens yderside, der strækker sig delvist gennem væggene. Perforeringen foretager man så i bunden 2 151163 af disse udsparinger, hvor godstykkelsen er ringe.The problem has been solved by making some large recesses on the outside of the mold that extend partially through the walls. Perforation is then carried out at the bottom 2 of these recesses where the thickness of the material is low.

Formålet med opfindelsen er at tilvejebringe en osteform, der på hensigtsmæssig måde kan fremstilles af plast. Denne opgave løses ifølge opfindelsen ved at ud-5 forme osteformen, således at den består af en indvendig kasse med forholdsvis ringe godstykkelse og en udvendig konstruktion af forstærkningsribber. Kassens godstykkelse kan nu gøres væsentligt ringere end den, der er nødvendig for at optage pressetrykket, idet dette opta-10 ges af forstærkningsribberne. Forstærkningsribberne kan også lægges på de steder, hvor belastningen er størst.The object of the invention is to provide a cheese mold which can be conveniently made of plastic. This task is solved according to the invention by forming the cheese mold so that it consists of an inner box of relatively small thickness and an outer structure of reinforcing ribs. The thickness of the box can now be made substantially inferior to that required to absorb the compressive pressure, as this is taken up by the reinforcing ribs. The reinforcing ribs can also be laid in the places where the load is greatest.

Da kassen har en forholdsvis ringe godstykkelse, er der ingen problemer med at lave en perforering, selvom kassen er af plast. Perforeringen kan laves med lasertek-15 nik eller med mere traditionelle perforeringsteknikker, såsom udstansning eller med varmetråde.Since the box has a relatively small thickness of material, there is no problem in making a perforation even if the box is plastic. The perforation can be done with laser techniques or with more traditional perforation techniques such as punching or with heating wires.

Hensigtsmæssigt laves osteformen således, at den indvendige kasse og den udvendige konstruktion af forstærkningsribber er to separate dele, hvor kassen kan 20 anbringes inden i ribbekonstruktionen. Den indvendige, forholdsvis billige kasse kan benyttes som holdeform.Conveniently, the cheese mold is made such that the inner box and the outer structure of reinforcing ribs are two separate portions where the box can be placed within the rib structure. The inner, relatively inexpensive box can be used as a holding mold.

Desuden har konstruktionen rengøringsmæssige fordele.In addition, the construction has cleaning benefits.

Kassen kan være et hele, men en anden mulighed er, at sidevæggene er hængslet til kassens bund, således at 25 sidevæggene kan foldes ud. Dette letter afformningen af ostene, samtidigt med at rengøringen lettes betydeligt, idet man blot skal rengøre et fladt emne. Man undgår således hjørnerne i kassen, som er vanskelige at rengøre .The box may be a whole, but another possibility is that the side walls are hinged to the bottom of the box so that the side walls can be unfolded. This facilitates the shaping of the cheeses, while considerably simplifying the cleaning process by simply cleaning a flat item. This avoids the corners of the box which are difficult to clean.

30 Hvis kassen er lavet af polypropylen, kan hængsel leddet på simpel måde bestå af en svækningsri1 le i overgangen mellem kassens bund og sidevægge. Dette har vist sig at 3 151163 være en effektiv og holdbar løsning. Det er imidlertid indlysende, at hængselkonstruktionen kan laves på anden vis .If the box is made of polypropylene, the hinge joint can simply consist of a weakening element in the transition between the bottom and the side walls of the box. This has proven to be an effective and durable solution. However, it is obvious that the hinge construction can be made differently.

Med hensyn til ribbekonstruktionen udgøres denne hen-5 sigtsmæssigt af U-formede ribber, hvis vandrette stykke understøtter kassens bund, og de lodrette stykker understøtter kassens sider. Man kan her forestille sig to sæt ribber, der krydser hinanden, idet det ene sæt løber på tværs af kassen, mens det andet forløber på 10 langs af kassen. Der kan laves indhak i ribbernes vandrette stykke, således at de ligger i et plan, samtidigt med at de fastlåser hinanden i indbyrdes stilling. En anden mulighed er, at de tværgående ribber ligger oven på de langsgående eller omvendt.Conveniently, with respect to the rib structure, this is constituted by U-shaped ribs whose horizontal piece supports the bottom of the box and the vertical pieces support the sides of the box. Here one can imagine two sets of intersecting ribs, one set running across the box while the other extending 10 along the box. Notches can be made in the horizontal section of the ribs so that they lie in a plane, while simultaneously locking each other in position. Another possibility is that the transverse ribs lie on top of the longitudinal or vice versa.

15 En hensigtsmæssig måde er, at der på den ene led af kassen er U-formede ribber, mens der på de to øvrige sider fortrinsvis enderne er ribber i form af lodret anbragte stænger. Derved undgår man problemet med krydsende ribber.A convenient way is that on one side of the box there are U-shaped ribs, while on the other two sides, preferably the ends are ribs in the form of vertically arranged rods. This avoids the problem of intersecting ribs.

20 ved en udformning af osteformen ifølge opfindelsen er ribberne samlet med vandrette gennemgående stænger, der er samlet i kassens hjørner. Stængerne optager således det tryk, der kommer, når ostemassen presses. Ribberne skal da blot føre trykket ud til stængerne.20 in one embodiment of the cheese mold according to the invention, the ribs are joined by horizontal through bars joined in the corners of the box. The rods thus absorb the pressure that comes when the curd is pressed. The ribs should then simply apply pressure to the rods.

25 Stængerne kan have en række indsnit, der passer til ribberne, men hensigtsmæssigt udgøres af de stagbolte, der sidder i pashuller i ribberne.The rods may have a number of incisions that fit the ribs, but are conveniently constituted by the stud bolts which are fitted in the fit holes in the ribs.

Ribberne holdes i indbyrdes afstand med afstandsstykker anbragt mellem ribberne. Ved brug af stagbolte udgøres 30 afstandsstykkerne hensigtsmæssigt af rørstumper, der skubbes ind over boltene.The ribs are spaced apart with spacers placed between the ribs. When using stud bolts, the 30 spacers are conveniently constituted by tubes which are pushed in over the bolts.

4 151163 I det følgende skal det på tegningen skematisk illustrerede udførelseseksempel for opfindelsen beskrives nærmere.In the following, the exemplary embodiment of the invention schematically illustrated in the drawing will be described in more detail.

Fig. 1 viser et længdesnit gennem osteformen; 5 fig. 2 viser et tværsnit gennem osteformen, og fig. 3 viser et hjørne af osteformen set fra siden .FIG. 1 shows a longitudinal section through the cheese mold; 5 FIG. 2 shows a cross section through the cheese mold, and FIG. 3 is a side view of the cheese mold.

Osteformen består af en indvendig kasse 1 med forholdsvis ringe vægtykkelse. Kasserne er af polypropylen, der 10 er et rengøringsvenligt materiale og meget modstandsdygtigt mod såvel kemikalier som temperaturpåvirkninger, samtidigt med at det umiddelbart giver mulighed for at lave et hængsel mellem kassens sider og bunden, således at siderne kan foldes ud. Dette letter arbejdet 15 med at tage osten ud af formen, samtidigt med at rengøringen gøres nemmere, idet det drejer sig om et plant emne og ikke en kasse, hvor hjørnerne kan være vanskeligt at rengøre.The cheese mold consists of an inner box 1 with relatively low wall thickness. The boxes are made of polypropylene, which is a clean-friendly material and very resistant to both chemicals and temperature effects, while at the same time allowing it to make a hinge between the sides of the box and the bottom so that the sides can be unfolded. This facilitates the work of removing the cheese from the mold, while at the same time making cleaning easier, because it is a flat item and not a box where the corners can be difficult to clean.

Ribbekonstruktionen 2, hvori kassen anbringes, udgøres 20 af et antal U-formede ribber 3, der er anbragt på tværs af kassen. De U-formede ribber 3 kan være samlet af to retvinklede stykker, hvis ene ben er svejst eller limet sammen. Vinkelstykkerne kan være standardkomponenter, der tilpasses kassens højde og bredde.The rib assembly 2, in which the box is placed, is constituted by a number of U-shaped ribs 3 arranged transversely of the box. The U-shaped ribs 3 may be composed of two right-angled pieces, one leg of which is welded or glued together. The angle pieces can be standard components that are adapted to the height and width of the box.

25 De U-formede ribber 3 er samlet med rustfrie stagbolte 4 anbragt i dertil beregnede pashuller 5 ved ribbernes bund og top. Imellem ribberne er der anbragt afstandsstykker 6 i form af korte rørstykker, der er skudt ind over stagboltene 4.The U-shaped ribs 3 are assembled with stainless steel bolts 4 arranged in the fitting holes 5 at the bottom and top of the ribs. Between the ribs are spacers 6 in the form of short tubes inserted over the stud bolts 4.

5 151163 I enderne udgøres ribbekonstruktionen ganske enkelt af lige ribbestykker 7 samlet på tilsvarende vis, som de U-formede ribber med stagbolte 4 og afstandsstykker 6.At the ends, the rib assembly is simply constituted by straight ribs 7 assembled in a similar manner to the U-shaped ribs with stud bolts 4 and spacers 6.

I hjørnerne er de langsgående stagbolte forsynet med et 5 hoved 8 med et hul 9 for stagboltene i enderne, der spændes med bolte.In the corners the longitudinal stud bolts are provided with a 5 head 8 with a hole 9 for the stud bolts at the ends which are tightened with bolts.

Det tryk kassen udsættes for, når ostemassen presses for uddrivning af vallen overføres via de jævnt fordelte ribber til stagboltene, som optager de kræfter som 10 formens sidevægge påføres.The pressure exerted by the box when the curd is pressed to expel the whey is transmitted via the evenly distributed ribs to the stud bolts which absorb the forces applied to the side walls of the mold.

Formene har mange fordele. De er bl.a. meget rengøringsvenlige, idet kassen 1 kan tages ud af ribbekonstruktionen 2, foldes ud og gøres rent som et plant emne. Ribbekonstruktionen er i sig selv nem at rengøre.The molds have many advantages. They include very easy to clean, since the box 1 can be removed from the rib structure 2, unfolded and cleaned as a flat item. The rib construction itself is easy to clean.

15 Afformningen er tillige lettet ved at kassens 1 sider kan foldes ud. Produktionsmæssigt er fremstillingen af formene enkel alene af den grund, at der kun indgår et fåtal grundelementer. Dernæst kan der frembringes forskellige størrelser på osteformene ud fra de samme 20 grundelementer. Perforeringerne i selve kassen er desuden nemmere at lave på grund af den ringe godstykkelse.The deformation is also facilitated by the fact that the sides of the box can be unfolded. In terms of production, the production of the molds is simple only for the reason that only a few basic elements are included. Next, different sizes of cheese forms can be produced from the same 20 basic elements. The perforations in the box itself are also easier to make due to the small thickness of the goods.

Hvor overfladen af osten er af særlig betydning, kan der anvendes indsatskasse af perforeret rustfrit stål i samme ribbekonstruktion af plast.Where the surface of the cheese is of particular importance, a perforated stainless steel insert box can be used in the same plastic rib construction.
