There are many ways to display your ice cream. The current fashion in Thailand is to clearly show inside a ice cream display with a big glass in order to see mountains of gelato decorated with fruits, cookies, toppings, flavors signs and even with sugar or plastic gadgets.
In this way you can save electricity but the sale will be lower. If you choose this way you can be happy with a more simple model of ice cream display as here the cold line does not have to be to high and you can be smart to decorate a little bit without giving a mountain shape to your gelato and still give a nice visual of your products to your customer like in the third image above here.
Using an ice cream cart can also be a solution, in this way you don't need to display much of the ice cream, better concentrate to the look and some signs.
Nowadays in Italy, the country of the "gelato" they are using an innovative
(well, it is an idea from the past) way to display ice cream: not to display
at all! In this way they save electricity, money, time as they don't have to
move the ice cream from the display freezer to the stock freezer and the
gelato is well preserved also from the light. Keep in mind that in Italy
there is a real culture of the gelato and people walk around looking for an
ice cream cone to stroll with. Here in Thailand you can also follow this trend. You will see the electricity bill reduced by 2,000 a month compare with a traditional display for ice cream.
