Method for producing biomass fuel and biomass fuel production system

Abstract

This method for producing a biomass fuel includes: a management step S130 for managing a carry-in date for a biomass to be carried into a stock yard; a dispensing step S140 for dispensing the biomass from the stock yard on the basis of the carry-in date; a squeezing step S160 for squeezing the biomass that has been dispensed by the dispensing step S140 to remove a squeeze liquid from the biomass; a first washing step S170 for washing the biomass that has been squeezed by the squeezing step 160 with water; and a first dehydrating step S180 for squeezing the biomass that has been washed by the first washing step S170 to dehydrate the biomass.

Claims

1. A management process for managing the date of felling of the oil palm or the date on which the fruit is removed from the oil palm as the date on which the EFB is brought into the stockyard, A dispensing process for dispensing the EFB within four days of the delivery date from the stockyard, A pressing step is performed to remove the juice from the EFB by pressing the EFB discharged in the aforementioned dispensing step, A first washing step in which the EFB compressed in the aforementioned pressing step is washed with water, A first dewatering step involves dewatering the EFB that has been washed in the first washing step by pressing it, A method for producing biomass fuel, including [the specified element].

2. A method for producing biomass fuel according to claim 1, wherein the heating step of heating the EFB before performing the pressing step is not included.

3. The method for producing biomass fuel according to claim 1 or 2, wherein in the pressing step, the water content of the EFB to be pressed is 50% by mass or more and 80% by mass or less.

4. The method for producing biomass fuel according to claim 1 or 2, wherein in the pressing step, the compressive force used to press the EFB is 30 MPa or more and 60 MPa or less.

5. A second washing step in which the EFB dehydrated in the first dehydration step is washed with water, A second dewatering step involves dewatering the EFB that has been washed in the second washing step by pressing it, A method for producing biomass fuel according to claim 1 or 2, further comprising:

6. A management device that manages the date of felling of oil palms or the date of extracting fruit from oil palms as the date of delivery of EFB to the stockyard, A dispensing device for dispensing the EFB within four days of the delivery date from the stockyard, A pressing device that removes the juice from the EFB by pressing the EFB dispensed by the aforementioned dispensing device, A washing device for washing the EFB compressed by the aforementioned pressing device with water, A dewatering device for dewatering the EFB that has been washed by the washing device by compressing it, A biomass fuel production system equipped with the following features.
