Abstract

Frying is performed in two stages so as to dip a retainer in frying oil at a prescribed dipping ratio and then to dip the whole of the retainer in the frying oil, and in addition, flow rates of the frying oil supplied from an upstream side and a downstream side of a frying oil tank and a surface level of the frying oil are controlled. Therefore, a noodle lump can be prevented from peeling off and floating from the bottom of the retainer before fixing the shape of the noodle lump due to a pressure applied by the frying oil so as not to impair the shape of the noodle lump, and as a result, frying efficiency or production efficiency can be improved. Besides, a noodle lump that has a very small number of coarse or dense portions in a distribution of noodle strings can be stably produced.

First claim

The invention claimed is:

1. A method for producing a fried noodle lump by dipping, in frying oil held in a frying oil tank, a retainer holding a group of noodle strings having been gelatinized, comprising:
a first conveying the retainer holding the group of noodle strings so that the group of noodle strings in the retainer is partially dipped at a lower part of the group of noodle strings, in the frying oil held in the frying oil tank and passes through the frying oil horizontally relative to a surface of the frying oil; and
following the first conveying, a second conveying of the retainer holding the group of noodle strings so that a whole part of the group of noodle strings is dipped in the frying oil held in the frying oil tank,
wherein a flow rate of the frying oil supplied from at least one ejection port provided on a bottom portion of the frying oil tank in an upstream portion thereof in a conveying direction of the retainer is in a range from 45.3% to 85% of a flow rate of the frying oil supplied from at least one ejection port provided on a bottom portion of the frying oil tank in a downstream portion thereof in the conveying direction,
wherein the frying oil that the group of noodle strings contacts while being present in the frying oil tank, consists of the frying oil in a state of being present in the tank, and
wherein the frying oil tank is a single tank.

2. The method for producing a fried noodle lump according to claim 1 , wherein a dipping ratio of the group of noodle strings in the frying oil in the first conveying is in a range from 10% to 70%, where the dipping ratio of the group of noodle strings is a ratio expressed in percentage obtained by dividing a height from a bottom of the retainer to a surface level of the frying oil by a height of the group of noodle strings.

3. The method for producing a fried noodle lump according to claim 1 , wherein a surface level of the frying oil in the upstream portion of the frying oil tank is lower than a surface level in the downstream portion of the frying oil tank.

4. The method for producing a fried noodle lump according to claim 1 , wherein a supply amount of the frying oil to be supplied to the frying oil tank is controlled based on a surface level of the frying oil in a region of the frying oil tank where the first conveying is carried out.

5. The method for producing a fried noodle lump according to claim 1 ,
wherein an extension plate is disposed downstream of the at least one ejection port provided on the bottom portion of the frying oil tank in the upstream portion thereof so as to prevent the frying oil flowing in the frying oil tank from directly hitting the retainer.

6. The method for producing a fried noodle lump according to claim 5 ,
wherein the extension plate includes a plurality of holes, and
wherein the frying oil ejected from the at least one ejection port provided on the bottom portion of the frying oil tank in the upstream portion thereof flows into the tank from left and right sides of the extension plate.

7. The method for producing a fried noodle lump according to claim 1 ,
wherein a time of the first conveying is in a range from 10 seconds to 30 seconds.
