3.1 General characteristics of the different models
The La San Marco grinders-dispensers are professional equipment designed for grinding and metering cof -
fee beans. La San Marco S.p.A. manufactures four basic grinder-dispenser models: SM 91; SM 96; SM MK;
SM FK. They are essentially made up of:
• A painted aluminium housing
1
. The size, shape and volume are identical for all models, except models
SM MK and SM FK, in which the standard housing is provided with a base
2
that contains the electrical
and electronic components.
• A hopper
4
, made of transparent plastic material, positioned on top of the grinder-dispenser. The hopper
4,6 litre is fixed to the grinder-dispenser by a special screw
8
. The hopper can only be removed with the
help of an appropriate tool. Inside the hopper there is a safety grid
7
that prevents the upper limbs from
accidentally coming into contact with the grinders.
• An electric motor on which the grinding unit is connected. On the grinder-dispenser unit, model SM MK,
an epicycloid reduction is connected between the motor and the grinding unit.
• A grinding unit. Model SM 91 and model SM 96 are equipped with a grinding unit with flat grinders of 64
mm and 84 mm diameter, respectively. Model SM MK has a grinding unit with one conical and two flat
grinders, while model SM FK has a grinding unit with conical grinders.
• A grind adjustment ring
12
with a release button
11
. The top of the ring shows the grinding adjustments
possible. The ring is turned clockwise or counterclockwise to change the fineness of the ground coffee.
• A dispenser
13
designed to measure and dispense the ground coffee; it has an adjustment range from 5
to 9 grams or, in the increased dose configuration, from 6 to 10 grams. The amount of ground coffee
dispensed can be adjusted by operating on the control knob
15
, located inside the dispenser.The ground
coffee is dispensed by pulling on the coffee dispensing lever
17
. The presser
16
, available on cylindrical
and conical versions, enables the ground coffee to be pressed down inside the filter cup.
• A support fork
18
for the filter cup.
• An electronic control unit that controls the coffee grinder start and stop. The grinding time can be pro -
grammed on the electronic control unit and the grinder-dispenser can be made to restart after a desired
number of ground coffee servings.
• An on/off main switch
3
with green LED.
