Claims (5)

1. En tandhjulspumpe, som omfatter en styreenhed (20) til adaptiv regulering af lukketryk af nævnte tandhjulspumpe, der omfatter en indløbstandhjulspumpe (10) af en iscremefryser (40), hvilken indløbstandhjulspumpe omfatter et pumpehus (11), et indløb (12) til modtagelse af et flydende fødevareprodukt af iscremeblanding, og udløb (15) til overførsel af iscremeblandingen ind i en frysecylinder (41) af iscremefryseren (40), kendetegnet ved, at indløbet (12) er forbundet med en impeller (13), som driver et stjemehjul (14), der igen er forbundet med udløbet (15), hvor pumpen (10) lukkes ved at tilføre et lukkelufttryk på et bevægeligt pumpedæksel (16) af pumpen (10) via mindst ét hul (191, 192), som er tilvejebragt lige gennem pumpehuset (11), hvorved nævnte bevægelige pumpedæksel (16) bevæges mod stjemehjulet (14), hvor styreenheden er konfigureret til at: modtage (21) en første mængde flydendefødevareprodukttilførselstryk (Pin, PI) ved pumpens (10) indløb (12), modtage (22) en anden mængde flydendefødevareproduktafgangstryk (Pout, P2) ved pumpens (10) udløb (15), beregne (23) et lukkelufttryk (Pclose), som bestemmes af differenstrykket mellem flydendefødevareproduktafgangstrykket (Pout, P2) og flydendefødevareprodukttilførselstrykket (Pin, PI) over pumpen (10), tilføre (24) det beregnede lukkelufttryk (Pclose) til det bevægelige pumpedæksel (16) ved hjælp af en lufttryksregulator (100) via det mindst ene hul (191, 192) i pumpehuset (11), hvorved det bevægelige pumpedæksel (16) tvinges mod stjemehjulet (14), hvorved pumpen (10) lukkes.
2. Tandhjulspumpen ifølge krav 1, hvor styreenheden er konfigureret til at beregne lukkelufttrykket under anvendelse af formlen: Lukkelufttryk [bar] = Dijferenstryk*0,5+0,5.
3. Tandhjulspumpen ifølge krav 1 eller 2, hvor tandhjulspumpen omfatter en indløbstandhjulspumpe og en udløbstandhjulspumpe, og styreenheden er anbragt i en enkelt enhed.
4. En fremgangsmåde (50) til adaptiv lukning af en tandhjulspumpe (30) til en iscremefryser (40), hvilken fremgangsmåde omfatter trinnene: modtagelse (51) af en første mængde flydendefødevareprodukttilførselstryk (Pin, PI, P2) ved et indløb (12) af pumpen (10), modtagelse (52) af en anden mængde flydendefødevareproduktafgangstryk (Pout, P2, P3) ved et udløb (15) af pumpen (10), beregning (53) af et lukkelufttryk, som bestemmes af differenstrykket mellem flydendefødevareproduktafgangstrykket (Pout, P2, P3) og flydendefødevareprodukttilførselstrykket (Pin, PI, P2) over pumpen (10), og tilførsel (54) af det beregnede lukkelufttryk til et bevægeligt pumpedæksel (16) af pumpen ved hjælp af en lufttryksregulator (100) via mindst ét hul (191, 192) i pumpehus (11) af pumpen, hvorved det bevægelige pumpedæksel (16) tvinges mod et stjemehjul (14) af pumpen, hvorved pumpen (10) lukkes.
5. Fremgangsmåden (50) ifølge krav 4, hvor trinnet til beregning af lukkelufttrykket udføres under anvendelse af formlen: Lukkelufttryk [bar] = Dijferenstryk*0,5+0,5.
